POLOMINTS

Polar Ocean Mixing by Internal Tsunamis

Start date
1 January, 2025
End date
31 December, 2029

The overarching goal of POLOMINTS is to determine the key mechanisms of internal tsunamigenesis across a wide range
of temporal/spatial scales of glacier calving and ocean conditions, and to quantify its impact on mixing, heat and nutrient
redistribution, marine productivity and carbon cycling.

POLOMINTS will produce three key outputs:-
1. Detailed mechanistic understanding of the forms/sizes of calving and fjord/shelf geometries most effective at generating
internal tsunamis, enabling advances in understanding of ice/ocean interactions in climatically-, biogeochemically- and
ecologically-important regions.
2. An assessment of the regional impacts of ocean mixing from internal tsunamis on the distributions and exchanges of
ocean heat, nutrients and carbon, and how this may change in future, enabling policy-relevant assessments of the
implications for climate, the cryosphere and ecology.
3. Knowledge of how to represent vigorous and episodic internal tsunami-driven mixing in ocean models, thus improving
model capability in relation to one of the most poorly-understood components of the Earth system

Underwater tsunamis focus of new study

19 November, 2024

An international research team, led by British Antarctic Survey (BAS), has been awarded £3.7M to advance a ground-breaking study on how underwater tsunamis are triggered by glacier calving around Antarctica. …
