Future climate of the Antarctic is a topic of concern to scientists and to the general public, and has implications for global sea level rise. This paper uses an ocean model driven by high-end atmospheric conditions plausible by late 23rd century to highlight what might happen to the Antarctic ice and its surrounding ocean if our emissions of CO2 continue to rise in an extreme way. The model suggests that the future Antarctic continental shelf would be more like the present day Amundsen Sea – warmer and fresher. This would lead to substantial increases in ice shelf melt rates.

There have been various recent papers linking internal waves/tides with cold water coral distribution and abundance. This is the first one, to the best of our knowledge, that approaches the question from a global context. The focus on biophysical interaction means that it may be of particular interest to the broad geoscience community.

This analytical study investigates the eddy energy dissipation rate for relative wind stress. The derived dissipation rate draws on our fundamental understanding of relative wind stress damping, vertical eddy structure, and eddy energy. The study suggests a method to parameterise the damping of total eddy energy in coarse resolution global climate models, and may have implications for a wide range of climate processes.

This paper, using pre-storm, immediate post-storm and recovery data, quantifies seafloor elevation and volume change within the Looe Key Reef system of the Florida Keys Reef Tract over a 2.5-year period from 2016–2019 and to examine impacts from category-4 Hurricane Irma and post-storm re-equilibration of seafloor sediments. The study highlights the need to data collected over seasonal and annual time periods to improve characterization and understanding of short-term (event-driven, seasonal, interannual) and long-term (decadal to multi-decadal) rates and processes of seafloor change and help guide benthic habitat post-storm recovery and restoration efforts in topographically complex coral reef systems.
