  1. Contemporary infrastructure projects in the sea reterritorialize port environments, continuously discarding historic occupants and coastal occupations in their wake. In this article the authors dwell on the ongoing histories through which fish and fishers are eviscerated in Mumbai's seas via the proliferation of massive infrastructural operations currently being staged by the Indian state. In so doing, they make two arguments. First, they show how infrastructures at sea are accretive forms that are simultaneously articulated at different time scales. New infrastructures currently being built in the sea in postcolonial India only intensify the expropriations of colonial projects that were staged in the sea. Second, urban fishers work not only at sea but also on the dry land of the city. As chances for making livelihoods at sea are steadily foreclosed, fishers are increasingly turning to their small parcels of land in the city, exploring how and if these might be made real estate to secure their futures.

  2. The sea ice of Article 234 of UNCLOS represents not the physical ice of the Arctic Ocean but a negotiated myth of ice as it affects the Arctic littoral states. The stability of this prescription is threatened by anthropogenic climate change causing a preferential evacuation of ice from the eastern Arctic compared to the western Arctic, as well as expectations for a possible future ice-free Arctic. This is leading to an intensification of claims on marine space. The irreducible uncertainties of the future trajectory of Arctic change demands a dynamic response. The myth of Article 234 will ultimately align with the complexities of the phenomenon of disappearing ice. It is in the dynamic nature of international law that prescriptions do not remain constant and neither does ice.

  5. Abstract The West Antarctic Ice Sheet is experiencing rapid thinning of its floating ice shelves, largely attributed to oceanic basal melt. Numerical models suggest that the Bellingshausen Sea has a key role in setting water properties in the Amundsen Sea and further downstream. Yet, observations confirming these pathways of volume and tracer exchange between coast and shelf break and their impact on inter‐sea exchange remain sparse. Here we analyze the circulation and distribution of glacial meltwater at the boundary between the Bellingshausen Sea and the Amundsen Sea using a combination of glider observations from January 2020 and hydrographic data from instrumented seals. Meltwater distributions over previously unmapped western regions of the continental shelf and slope reveal two distinct meltwater cores with different optical backscatter properties. At Belgica Trough, a subsurface meltwater peak is linked with hydrographic properties from Venable Ice Shelf. West of Belgica Trough, the vertical structure of meltwater concentration changes, with peak values occurring at greater depths and denser isopycnals. Hydrographic analysis suggests that the western (deep) meltwater core is supplied from the eastern part of Abbot Ice Shelf, and is exported to the shelf break via a previously‐overlooked bathymetric trough (here named Seal Trough). Hydrographic sections constructed from seal data reveal that the Antarctic Coastal Current extends west past Belgica Trough, delivering meltwater to the Amundsen Sea. Each of these circulation elements has distinct dynamical implications for the evolution of ice shelves and water masses both locally and downstream, in the Amundsen Sea and beyond.
