Coastal Ocean Dynamics in the Arctic (CODA): oceanographic moorings from 2019-2020 along the northern coast of Alaska

This dataset contains mooring observations of ocean waves, currents, and temperatures, as well as sea ice thickness, at three coastal sites along the northern coast of Alaska, with multiple cross-shore positions at each site. The data documents the annual cycle of the coastal environment, with wave activity and warm temperatures in the summer and fall, then ice cover and cold temperatures in the winter and spring. The cross-shore variations include the effects of land-fast ice (at positions close to the coast). The data were collected as part of the Coastal Ocean Dynamics in the Arctic (CODA) project, and the motivation of the project was to understand the oceanographic drivers of coastal erosion in the Arctic. Our methods emphasized in situ measurements of ocean surface waves, sea ice thickness, and water temperatures. We used seafloor platforms (moorings) to collect these data, with uplooking Acoustic Doppler Current Profilers and Altimeters as well as seafloor temperature and pressure.
