4. Coastal buoyancy controls on multiple melt regimes of warm West Antarctic ice shelves

Author

Moorman, Ruth, Thompson, Andrew F, and Wilson, Earle A

Abstract

Mass loss from the West Antarctic Ice Sheet is currently dominated by discharge through ice shelves exposed to warm modified Circumpolar Deep Waters (mCDW). Basal melt rates in these regions track decadal scale oscillations in the depth of the thermocline separating mCDW from cooler near-surface waters. Prior work has attributed the observed thermocline depth variability to wind-driven variations in shoreward mCDW transport. Here, we show that transformation of mCDW in coastal polynyas also impacts mCDW thickness variability, and we compare the importance of this mechanism to shelf break wind forcing.We introduce a simple overturning circulation model for the continental shelf that distinguishes between thermocline depth variability associated with mCDW supply and mCDW transformation. This model indicates that surface buoyancy fluxes within coastal polynyas can generate large decadal variations in thermocline depth in the absence of variable mCDW inflow, posing an alternative mechanism for observed mCDW thickness variability. The modeled variability takes the form of transitions between bistable high and low melt regimes, made possible by feedbacks between basal ice melt and stratification at the ice front. Our simple model can explain both the magnitude of observed thermocline depth variations and their lagged correlation with stratification strength, which are not fully accounted for in work focussed on wind forcing. The work suggests a previously underestimated role for coastal polynya dynamics in setting the melt rates of West Antarctic ice shelves and demonstrates the utility of framing the transport of ocean heat towards ice shelves in terms of an overturning circulation., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

25. "From Lab to Market": Embracing a Paradigm Shift at Jamaica' National University via Value Capture from Innovative Research Results.

Abstract

In this paper, reflection and the scholarship of integration are used to highlight, using a recent example of an internally-funded project, how the University of Technology, Jamaica is embracing a paradigm shift by capturing for commercial exploitation by industry the value that inheres in research results. The role of the university's research management office as a helpful intermediary, the lessons learnt, and the "pathway to impact" - where evidence of the translation of research into impacts is usually manifested - of the cited example are also discussed. It is concluded that taking the results of this research project from "lab to market" holds extremely important lessons for other researchers at UTech, Jamaica, students of the university, and the wider Jamaican society in that the actions taken together represent a "live" demonstration of the process of converting science into tangible value that has income-earning potential (i.e., "capitalization of science").
