DOI: 10.1002/2016jc012452
Abstract: Observations made on 21 occupations between 1993 and 2016 of GO-SHIP line SR1b in eastern Drake Passage show an average temperature of 0.53°C deeper than 2000 dbar, with no significant trend, but substantial year-to-year variability… read more here.

DOI: 10.1029/2019pa003773
Abstract: The Antarctic Circumpolar Current (ACC) is the world's largest current system connecting all three major basins of the global ocean. Our knowledge of glacial‐interglacial changes in ACC dynamics in the southeast Pacific is not well… read more here.

DOI: 10.1029/2024gl111455
Abstract: Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula. Here, new… read more here.

DOI: 10.1029/2025pa005100
Abstract: The Miocene Epoch (23.03–5.33 Ma) is receiving increased attention because estimated pCO2 and its associated warmth is comparable to projections over the next century. Well‐constrained sea‐surface temperatures in the tropics and northern latitudes express amplified… read more here.

DOI: 10.1080/14772019.2017.1393019
Abstract: Twelve genera and 19 species of deep-sea ostracods from the Shatsky Rise, north-western Pacific, were examined and illustrated for taxonomy. Three new species, Cytheropteron nasutum sp. nov., Poseidonamicus shatskyensis sp. nov. and Legitimocythere stellae sp.… read more here.

DOI: 10.1175/jpo-d-18-0150.1
Abstract: The dynamics of an oceanic storm track—where energy and enstrophy transfer between the mean flow and eddies—are investigated using observations from an eddy-rich region of the Antarctic Circumpolar Current downstream of the Shackleton Fracture Zone… read more here.

Revisiting Thorpe scale analysis and diapycnal diffusivities in Drake Passage
Sign Up to like & getrecommendations! Published in 2024 at "Frontiers in Marine Science"
DOI: 10.3389/fmars.2024.1444468
Abstract: Ship heave effects in the swell-prevalent Southern Ocean induce frequent false overturns in density profiles, and conventional Thorpe scale analysis leads to unrealistically large diapycnal diffusivities. Another critical factor causing large positive biases in Thorpe… read more here.
