Glider Observations in the Gulf Stream: Operations and analyses in support of NESMA
Abstract
Abstract (Approved for Public Release):This proposal seeks to conduct autonomous underwater glider surveys between the US East Coast and the New England Seamounts in support of the on-going New England Seamount Acoustics (NESMA) DRI. The new glider surveys will build on similar surveys conducted during the 2021-2024 field seasons, providing additional high-resolution observations of hydrography and circulation within and upstream of an existing array of acoustic transceiver moorings. The proposal also seeks support for new analyses of observations collected as part of the NESMA DRI. In particular, analyses will focus on 1) inferring the three-dimensional sound speed field by combining satellite-based remote sensing of sea surface properties and climatological subsurface properties, 2) understanding shifts in acoustic ducts due to changes in properties of subtropical mode water, and 3) determining the impact ofwaters entrained from the continental shelf into the Gulf Stream on acoustic propagation across the Gulf Stream front.
