Basal melt of ice shelves is not only an important part of Antarctica's ice sheet mass budget,
but it is also the origin of platelet ice, one of the most distinctive types of sea ice. In many …

Since landing at Gale crater, Mars, in August 2012, the Curiosity rover has searched for
evidence of past habitability, such as organic compounds, which have proved elusive to …

The salinity and water oxygen isotope composition (δ18O) of 29 first‐year (FYI) and second‐
year (SYI) Arctic sea ice cores (total length 32.0 m) from the drifting ice pack north of …

It has been known that groundwater-lake water interaction plays an important role in mass
exchange between land and lakes. However, most of the lakes in the world freeze during the …

To reduce uncertainties in future sea level projections, it is necessary to closely monitor the
evolution of the Antarctic ice-sheet. Here, we show that seawater oxygen isotopes are an …

The Arctic Ocean is an exceptional environment where hydrosphere, cryosphere, and
atmosphere are closely interconnected. Changes in sea-ice extent and thickness affect …

The isotopic analyses (δ 13 C, δ 18 O, and Δ 47) of carbonate phases recovered from a core
in McMurdo Sound by ANtarctic geologic DRILLing (ANDRILL-2A) indicate that the majority …

During a research expedition in Hudson Bay in June 2018, vast areas of thick (> 10 m),
deformed sediment-laden sea ice were encountered unexpectedly in southern Hudson Bay …

The hydrological cycle is expected to intensify in a warming climate. However, observational
evidence of such changes in the Southern Ocean is difficult to obtain due to sparse …

We analyzed biogeochemical components of brash ice, originating from sea ice and
icebergs, collected in the Indian sector of the Southern Ocean during the summer and …
