    Tropical coral reefs are restricted to the photic zone and are therefore particularly exposed to Quaternary sea level changes. The Great Barrier Reef of Australia (GBR), the largest and most diverse reef ecosystem in the world, was affected by multiple cycles of glacioeustatic sea level rises and falls. A combination of scientific coring studies, bathymetric and seismic surveys, have shown that the GBR periodically developed on the continental shelf during relative sea level highstands (HST reefs) and was restricted to the shelf edge during glacial sea level lowstands and subsequent deglaciations (LST-DGL reefs). Information on the HST reefs comes mainly from two deep boreholes drilled in 1995 in Ribbon Reef 5 (RR5) and Boulder Reef (BR) in the northern GBR (International Consortium for GBR drilling). The RR5 borehole (210 m) is located near the shelf edge whereas the BR borehole (86 m) was drilled further inshore in a protected muddy inner shelf reef 15 km from the coast. Webster and Davies (2003) identified several stacked reef generations and suggested the timing of the GBR initiation occurred at 452-365 ka. More recently, 34 boreholes were drilled into LST-DGL reefs, now submerged, along four transects at three localities along the shelf edge of the GBR (IODP Expedition 325, Webster et al., 2011): Hydrographers Passage (HYD-01C and HYD-02A), Noggin Pass (NOG-01B), and Ribbon Reef (RIB-02A). Here we integrate the coral data from all these boreholes to provide a full picture of the evolution of coral communities in the GBR during multiple cycles of sea level changes and to identify the factors controlling the coral community structure of the GBR during the Late Quaternary.

    IODP Expedition 325 drilled 34 boreholes into submerged reef structures along the shelf edge of the Great Barrier Reef (GBR). The boreholes were drilled between 42 and 167 mbsl at 17 sites along four transects at three geographic locations (Hydrographers Passage, Noggin Pass, and Ribbon Reef). The last glacial to deglacial reef sequence (~8 ka to ~27 ka) varies in thickness from ~5.5 m to ~34 m and consists primarily of coralgal boundstone with various proportions of microbialite. We use a detailed chronostratigraphic scheme based on numerous C14 and U-Th ages to discuss the evolution of the coralgal communities since the last glaciation. Exp. 325 cores show that different phases of sea level change promoted different shallow reef-building coral species at the study sites. The onset of the deglacial (16-19 ka) is characterized by a peak abundance of Seriatopora and Tubipora whereas the following rapid sea level rise (<16 ka) is marked by the dominance of massive Isopora and Acropora with medium- to robust-size branches. The shift in composition of coral communities around 16 ka coincides with the flooding of a pre-LGM MIS2 reef terrace, an event which had a major influence on reef growth and reef composition. We discuss the impact of this event on coralgal communities in the GBR and its significance for Quaternary reef evolution in general.

    The Great Barrier Reef (GBR) of Australia is the largest and most diverse reef ecosystem in the world. Coral cover declined significantly in recent years due to a combination of biological and climatic factors (De'ath et al., 2012). Yet, the GBR as a whole displayed a remarkable resilience during glacial-interglacial cycles, repeatedly reestablishing itself after multiple episodes of emersion (Webster and Davies, 2003). But the particular response of coral communities to Quaternary climate changes remains poorly documented. In an attempt to understand how coral communities responded to long-term natural perturbations, we reexamine two deep boreholes drilled in 1995 in the Ribbon Reef 5 (RR5) and Boulder Reef (BR) at latitude 15°24' S in the northern GBR (International Consortium for GBR drilling). The RR5 core (210 m) is located near the shelf edge 50 km off the Queensland coast and is directly exposed to the ocean swell. The BR core (86 m) was drilled further inshore in a protected muddy inner shelf reef only 15 km from the coast. Webster and Davies (2003) have used the RR5 core to constrain the age of the GBR inception to 452-365 ka (MIS 11) and reported two recurrent coral assemblages in this core and another distinct assemblage in the BR core. However, the details of the coral succession in these cores have not been fully investigated yet. Here we present an in-depth analysis of the variations in coral assemblages in the RR5 and BR cores during the entire history of the GBR. Our aim is to (1) document the initial phase of colonization, (2) evaluate the similarity in taxonomic composition between successive reef-building episodes, (3) examine the influence of terrigenous input on coral communities and their evolution, and (4) compare the coral record of the RR5 and BR cores with that of the IODP 325 cores drilled in submerged reefs along the shelf edge of the modern GBR (Webster et al., 2011).

    Reef corals and other benthic reef organisms, such as coralline algae, exhibit a non-random distribution along gradients of wave energy and light, i.e. reef zonation (Done, 1983). Fossil reef communities can therefore be used for paleoenvironmental and sea level reconstructions (Montaggioni and Braithwaite, 2009). However, our understanding of the present-day distribution of reef organisms is mostly limited to the shallower reef ecosystem (0-30 m). The deeper reef ecosystem, from 30 m to the bottom of the photic zone, i.e. the mesophotic reef zone, remains largely unexplored. From a biological viewpoint, the mesophotic reef zone is interesting because its exploration can lead to the discovery of new species (Petrescu et al., 2014). It has also an important ecological significance because it marks the transition between photic and non-photic ecosystems. Furthermore, the mesophotic reef zone has been considered a possible refuge for shallow-water species in times of environmental stress (Bongaerts et al., 2010). From a geological viewpoint, the importance of the mesophotic reef zone is twofold: (1) mesophotic reef organisms can be potentially useful paleoenvironmental and sea level indicators, and (2) the seafloor topography in the mesophotic reef zone is the product of the interplay between erosion and reef growth, controlled by eustatic sea level changes, subsidence and uplift.
    In 2004 and 2005, video images of the seafloor acquired by a small remotely operated vehicle (ROV) near the Sekisei Lagoon indicate the presence of distinct macrobenthic communities at depths of 30 to 120 m exhibiting a non-random distribution along a depth gradient (Furushima et al., 2005; Humblet et al., 2009). In addition, high-resolution bathymetric data have brought to light a number of interesting topographic features: a ridge and furrow system, gentle slopes and steep escarpments, prominent pinnacles, and mound-like structures. The variety of habitats and associated biota makes the forereef slope of the Sekisei barrier reef an ideal site for conducting a detailed study of the mesophotic reef zone and explore the relationship between seafloor topography and past sea level changes in this region.

    Drilling into submerged reef structures along the shelf edge of the Great Barrier Reef was carried out during IODP Expedition 325 with the purpose of reconstructing sea level and environmental changes since the Last Glacial Maximum (LGM) and analyzing their impact on reef communities and reef growth. A total of 34 boreholes were drilled between 42 and 167 mbsl at 17 sites along four transects at three geographic locations (Hydrographers Passage, Noggin Pass, and Ribbon Reef). Two basic chronostratigraphic units can be recognized: a last glacial to deglacial reef sequence overlying older Pleistocene reefal and non-reefal deposits. The former varies in thickness from ~5.5 m to ~34 m and consists primarily of coralgal boundstone with various proportions of microbialite. In this study we analyze the variations in coral assemblages since the last glaciation. Exp. 325 cores show that diverse corals, including Faviids, Acropora, Montipora, and Porites, were growing during the last glacial period on the shelf edge. Their distribution was limited to the most distal boreholes during the LGM lowstand. The subsequent deglaciation saw the development of a shallow-water coral assemblage dominated by encrusting to massive Isopora and branching Acropora and Seriatopora as sea level rose. The tops of distal boreholes are marked by a shift to deeper assemblages dominated by encrusting Porites and Montipora reflecting reef drowning and the formation of submerged reef terraces. As sea level kept rising, a shallow-water Isopora-dominated assemblage re-established further upslope and formed a barrier reef before drowning in turn.

    Mesophotic coral ecosystems (MCEs) are usually found at depth ranging from 30 to over 100 m depth. Mesophotic coral communities are often composed of both eurybathic tolerant species and species adapted to specific condition of the mesophotic zone. The taxonomic composition of such communities is still poorly known, yet important to conduct accurate paleoenvironmental interpretations of fossil reef deposits, especially in studies aiming to reconstruct past sea-level changes. Moreover, from a biological perspective, the Deep Reef Refugia Hypothesis (DRRH) states that mesophotic coral ecosystems, due to their more stable environmental conditions, may act as refugia for shallow water species to survive extreme climatic events and re-colonise shallower reefs in the future.
    Recent global environmental changes affected seriously shallow coral reefs around Okinawa. The combination of major bleaching events and several typhoons lead to changes in coral communities with some species apparently extinct from several locations. Around Sesoko Island in the northern part of Okinawa, several corals species disappeared since 1999 and were not recorded since then (van Woesik et al. 2011). Seriatopora hystrix was one of those species.
    During the recent survey of a mesophotic coral ecosystem located between Sesoko Island and Motobu Peninsula, high coral diversity and dense communities were found between 35 and 55 m depth including abundant populations of S. hystrix between 39 and 47 m. In order to estimate the coral biodiversity as well as the relationships between shallow and mesophotic corals, several genetic markers, both nuclear and mitochondrial, were sequenced for the samples collected. Symbiotic dinoflagellates were also identified. Here we will present the results of the molecular analyses showing the important coral diversity in this location. Our results also show intraspecific diversity within the population of S. hystrix. The genotypes of those deep populations correspond to genotypes previously observed from shallower reefs as well as to new genotypes. Such results suggest an absence of vertical structuring in Okinawan S. hystrix populations and support the (DRRH). In the future, and if shallow environmental conditions become suitable again for this species, deep populations of S. hystrix might be of critical importance for the re-colonisation of shallow coral reefs.

    In August 2009, dredging operations were carried out ~8 km southwest of Kikai-jima with the main objective of finding fossil reef material (RV Tansei-maru cruise KT-09-16). Seafloor material was collected along 14 transects (~200 to ~600 m in length) at depths ranging from 60 to 140 m (edge of the island shelf). Most of the material recovered consisted of macroids, coral gravels (thickly encrusted and bioeroded), and bryozoan-rich calcareous sand (at the deepest site). Live material consisted mainly of soft corals, gorgonians, and sponges. Thirteen live coral colonies were collected between 70 to 80 m water depth. Among these corals, ten belong to the genus Montipora, two to the genus Leptoseris, and one to the genus Echinophyllia. All colonies are a few centimeters across (max width of 11 cm), very thin (1 to 6 mm), and laminar with free margins. We provide a detailed description of the macro- and micromorphology of Montipora colonies based on optical and SEM imaging. Despite the limited number of colonies studied, analysis of morphological features such as corallite diameter, inter-corallite distance, spinule density and shape, shows that at least two morphological types can be distinguished. We compare the morphological characteristics of the recovered mesophotic Montipora with those of shallow species described in the literature.

    Major goals of the Integrated Ocean Drilling Program (IODP) Expedition 325 (GBREC: Great Barrier Reef Environmental Changes) include reconstructing histories of sea-level change, sea surface temperature variation and reef growth since the Last Glacial Maximum (LGM), and analyzing responses of reef-building corals to post-glacial sea-level rise. Cores were extracted from submerged reef structures along four transects in three localities on the shelf margin, seaward of the modern Great Barrier Reef. 225 m of drill-core were retrieved from 34 holes at 17 sites in depths from 42 to 167 m below present sea level, and from 1.5 to 42 m below the sea floor.
    Seven coral assemblages are defined, based on taxonomic and morphological compositions. Their paleoenvironments, by analogy with modern reefs, range from shallow wave-exposed to deep low-energy reef habitats. The initial post-glacial reef assemblage is dominated by shallow-water massive-submassive-branching Isopora with branching Acropora and thin branching Seriatopora. The deeper assemblages consist mainly of encrusting to submassive Montipora and encrusting Agariciidae. Horizontal differences between proximal and distal cores along transects probably reflect changing geomorphological and hydrodynamic regimes across the reef tract as sea level rose. Vertical changes in coral assemblages within a core reflect deepening of the water, leading to ultimate drowning of the coral community and creation of the tops of the submerged reef structures. As sea level rose, shallow reef assemblages re-established further upslope and accumulated several meters of reef structure before drowning in turn.

A total of 34 boreholes were cored at 17 sites ranging in depth from 42 to 167 meters below present sea level.

Their paleoenvironments are inferred by comparison with modern coral communities of the Great Barrier Reef and range from shallow wave-exposed to deep low-energy reef habitats. The initial post-glacial coral assemblage is dominated by shallow-water massive-submassive-branching Isopora associated with branching Acropora and Seriatopora. The deeper assemblages consist mainly of encrusting to submassive Montipora and encrusting Agariciidae. Horizontal changes in coral assemblages along transects, from proximal to distal cores, probably reflect the changing reef geomorphology and hydrodynamic regime during sea level rise. Vertical changes within a core reflect an increase in water depth followed by a drowning of the coral community and the formation of the submerged reef tops. As sea level rose, shallow reef assemblages re-established further upslope and accumulated several meters of reef structure before drowning in turn.

    During FY2019 the present research project focused on the description and interpretation of Quaternary fossil coral assemblages in the Ryukyu Islands based on examination of both outcrops and cores.
    Outcrops of late Middle Pleistocene coral limestones were examined at Horikawa quarry, southern Okinawa-jima, in October 2019. This study is part of a Nagoya Univ. student’s Master thesis and is conducted in collaboration with Prof. Kazuhiko Fujita (Univ. of the Ryukyus). The purpose of this study is to reconstruct the depositional history of the limestones of the late Middle Pleistocene Minatogawa Formation based on our understanding of the distribution of modern biota and sediments in the Ryukyu Islands. A detailed description of the coral species taxonomic and morphologic compositions of the limestones was carried out. Samples were collected for taxonomic and sedimentological analyses. Data from the four transects combined with those of previous surveys suggest a sea-level history more complex than previously thought.
    In addition, the description of five cores taken from Kodakara-jima, South Ryukyus, began in July 2019. The cores were drilled by the COREF project and are now stored at the Kochi Core Center. The purpose of this study is to examine the responses of high-latitude coral communities to sea-level and environmental changes during the various stages of Holocene reef development.
    In parallel to the aforementioned studies, analysis of the video images of mesophotic seafloor acquired along the margins of the Sekisei Lagoon, South Ryukyus, during past surveys is ongoing.
    The study of the COREF cores is slightly delayed due to additional time spent on the investigation of outcrops of Pleistocene coral limestones in southern Okinawa-jima.
    The following research activities related to the present project are expected to take place during FY2020:
    (1) The study of the cores from Kodakara-jima will continue this year. This is now the main theme of a Master thesis at Nagoya University. The description of the cores will be carried out at the Kochi Core Center.
    (2) An additional field survey in Southern Okinawa-jima targeting the limestones of the Minatogawa Formation is being planned. The survey will focus on stratigraphic intervals which have not yet been studied in detail.
    (3) One more survey of the modern mesophotic seafloor around the Sekisei Lagoon using robotic submersibles (i.e., ROV, AUV) will be scheduled in order to complement the existing data base on the distribution of biota and sediments at mesophotic depths around the Sekisei Lagoon.
    (4) A fossil mesophotic reef sequence sampled by IODP Exp. 325 will be examined at the Kochi Core Center to study the response of mesophotic coral communities to rapid deglacial sea-level rise.

    The goal of this seminar is to (1) teach students how to search for scientific information, (2) encourage critical thinking, (3) improve presentation skills, (4) nurture scientific curiosity; and (5) promote exchange of ideas about various scientific topics. The seminar is divided into two parts. The first part provides tips on how to search for information and how to give an oral presentation. A few lectures on coral reef ecosystems will serve as examples of how science can be communicated. The students will learn about the different kinds of reefs, the biology of corals and coral reefs, the factors controlling reef growth, the present-day threats on coral reefs, and the geological evolution of reefs. Students will also be able to examine hand-sized samples of coral reef limestones and observe thin sections under a microscope. During the second part of the seminar, the students will give two presentations each about any scientific subjects of their choice related to the marine or freshwater world. The fields covered can be as varied as underwater exploration technologies, marine biology, liquid water in the solar system, hydroelectric energy… Each presentation is followed by a Q&A session. Class participation is strongly encouraged.

  5. Fundamentals of Earth Science I

    2011

     詳細を見る

    The study of planet Earth embraces a wide range of topics, from the formation of rocks to the evolution of life. In this course, we will talk about plate tectonics, the fundamental theory underlying all geological processes which have shaped the environment in which we live and continue to modify the landscape, from the slow and progressive uplift of mountain chains to violent earthquakes and volcanic eruptions. The students will learn how the Earth recycles matter and how minerals and rocks form and are transformed. One chapter of the course is dedicated to the issue of time, central in earth science, and tackles the question of how the age of rocks and geological events can be determined. We will then take a step back and look at Earth’s 4.5 billion year history to see how the Earth’s geography has changed and how life has evolved.
    Besides providing a basic and up-to-date knowledge of the essential concepts of earth science, the aim of this course is to stimulate the students’ interest and curiosity for the study of planet Earth and provoke questions, comments, and discussions about issues related to earth science.
