This project received funding from the following: Bipartisan Infrastructure Law (Infrastructure Investment and Jobs Act).

High sea ice concentrations in the Chukchi Sea have prevented scientists from deploying instruments in the region, leading to a wide data gap. The RISE Mooring Project will deploy new and additional instruments in the Chukchi Sea, facilitating the collection of new metrics such as fluxes and productivity across the U.S. Arctic. During ice-free seasons, moorings are equipped with surface floats and will be equipped with meteorological sensors in the third year. Moorings also include a PRAWLER (PRofiling crAWLER), a wave-powered profiling system that ascends to the near surface and collects data as it free-falls along a cable. The system currently measures ocean temperature, salinity, oxygen, fluorescence, and pressure, with all data transmitted to the surface float and relayed back to PMEL.

Milestones

  1. Year 1: Ensure the functioning of the float component of the RISE mooring and collect temperature data in the southern Chukchi Sea (specifically C12 in DBO 3)
  2. Year 2: Parts for the second RISE mooring will be obtained and prepared for deployment at M14 (northern Bering Sea). A RISE mooring will be redeployed at C12. Pop-up floats will be deployed each year in the Chukchi Sea to improve cross-shelf resolution in this under-sampled region and collect under-ice data.
