Abstract Data from International Ocean Discovery Program (IODP) Expedition 371 reveal vertical movements of 1–3 km in northern Zealandia during early Cenozoic subduction initiation the western Pacific Ocean. Lord Howe Rise rose deep (∼1 km) water to sea level and subsided back, with peak uplift at 50 Ma north between 41 32 south. The New Caledonia Trough 2–3 55 45 Ma. We suggest these elevation changes resulted crust delamination mantle flow that led slab formation. propose a “subduction...
Direct observations of marine ecosystems are inherently limited in their temporal scope. Yet, ongoing global anthropogenic change urgently requires improved understanding long-term baselines, greater insight into the relationship between climate and biodiversity, and knowledge evolutionary consequences our actions. Sediment cores can provide this understanding by linking data on responses of marine biota to reconstructions past environmental climatic change. Given continuous...
Abstract Motivation We have little understanding of how communities respond to varying magnitudes and rates environmental perturbations across temporal scales. BioDeepTime harmonizes assemblage time series presence abundance data help facilitate investigations community dynamics timescales the response natural anthropogenic stressors. includes terrestrial aquatic assemblages spatial grain extent from present‐day millions years ago.

The region with the highest marine biodiversity on our planet is known as Coral Triangle or Indo-Australian Archipelago (IAA)
Abstract The Sea of Japan is a marginal sea, connecting to adjacent seas by four shallow straits (water depths <130 m). Marginal are ideal for studying biotic responses large‐scale environmental changes as they often sensitive glacial‐interglacial and stadial‐interstadial climatic cycles. However, only limited number studies cover time periods beyond the last two Here we present 700,000‐year record benthic response paleoceanographic in southern Japan, covering past seven cycles, based on...
Abstract Aim Within the intensively‐studied, well‐documented latitudinal diversity gradient, deep‐sea biodiversity of present‐day Norwegian Sea stands out with its notably low diversity, constituting a steep gradient in North Atlantic. The reason behind this has long been topic debate and speculation. Most prominently, it is explained by glacial disturbance hypothesis, which states that harsh environmental conditions negatively impacted diversities, have not yet fully recovered. Our aim to...
Records of relative sea-level rise for the last deglaciation are mostly limited to coral reef records and geophysical model estimates, but observational data from regions with temperate climates is sparse. We present a new climatic regional record glacial Termination 1 (Marine Isotope Stages [MIS] 2–1) based on ostracode paleoecology upper 8 m International Ocean Discovery Program (IODP) Site M0080 collected Expedition 381, in Gulf Alkyonides, eastern Corinth basin Mediterranean Sea.

Abstract Deep-sea benthic ostracod assemblages covering the last 2 Myr were investigated in Integrated Ocean Drilling Program Site U1426 (at 903 m water depth) southern Sea of Japan. Results show that (1) orbital-scale faunal variability has been influenced by eustatic sea-level fluctuations and oxygen (2) secular-scale transitions are likely associated with mid-Brunhes event (MBE, ~0.43 Ma) onset Tsushima Warm Current (TWC, ~1.7 Ma). Krithe , Robertsonites Acanthocythereis three most...
Abstract The East Asian winter monsoon (EAWM) is associated with northerly surface winds affecting crop and livestock productivity social economic activities across Asia. However, the relationship between EAWM dynamics marine biota remains poorly understood. In this study, we analyzed fossil ostracods from sediment cores collected in northwestern Pacific Ocean to detect appearance/disappearance of circumpolar species during late Quaternary. We compared our ostracod records, including dating...

Abstract Past intensity of methane release from deep-ocean hydrates continues to be challenging reconstruct reliably. Here, we used fossil ostracode fauna paired with foraminiferal δ13C values in a marine sediment core Vestnesa Ridge, western Svalbard margin, seepage activity during the late Quaternary and examine faunal response deglacial climatic changes. Benthic indicate was relatively strong isotope stage 2, corresponding high percentage Rosaliella svalbardensis assemblage. In contrast,...
