Ikaaġvik Sikukun

Native Village of Kotzebue, Arctic Alaska.

The Ikaaġvik Sikukun (Inupiaq for “Ice Bridges”) project employs the principles of knowledge co-production, bridging the scientific and Indigenous communities to study the changing sea ice environment of Kotzebue Sound, guided by the Traditional Knowledge of an Indigenous Elder Advisory Council. My primary role in the project was to investigate the causes of the extremely anomalous low-ice winters that occurred during our study period using in-situ observations of the heat flow between ocean, river, ice, and atmosphere in Kotzebue Sound.

The Response of Ocean Skin Temperature to Rain

Research Vessel Revelle, Indian Ocean

Using a 4-month-long dataset of radiometric skin temperature measurements made during 69 rain events, we tested a state-of-the-art model for the effect of rain on the temperature of the ocean surface, and demonstrated a physical modification to the model that greatly improved its agreement with observations. The quantitative understanding gained in this study of the physical relationship between rain and skin temperature is critical to studies of atmospheric circulation patterns and prediction of global weather and climate, as well as interpretation of satellite remote sensing measurements.

Radiant Heating of the Upper Ocean in the Presence of Near-Surface Material

Deep Water formation in Terra Nova Bay polynya

Ice-Breaking Research Vessel Araon, West Antarctica

In collaboration with the Korea Polar Research Institute’s LIONESS project, we installed a heavily instrumented oceanographic mooring in the Terra Nova Bay polynya, a ‘sea ice factory’ where some of the world’s densest water forms before flowing off the Antarctic continental shelf into the abyssal Southern Ocean. Check out some preliminary results from this work on Una Miller’s poster at AGU Fall Meeting 2020!

The TKE budget across the air-sea interface

Air-Sea Interaction Tower, Martha's Vineyard Coastal Observatory

We have succesfully completed a winter of measurements on the ASIT tower, and data analysis is underway. Lindsay Hogan presented work on the scaling of TKE by whitecap fraction at AGU Fall Meeting 2022.
