An enhanced current meter was deployed in the Antarctic in March, 2017, to measure vertical heat flux in the deep ocean. The purpose of this measurement of flux is to understand how mixing of dense Weddell Sea Bottom Water becomes Antarctic Bottom Water (AABW), the densest water of the Atlantic Ocean outside of trenches. Deep mixing is one of the problems that is not yet well understood despite its...
The surf-zone presents unique challenges and opportunities for observational oceanography. Physical and biogeochemical signals change quickly in and around breaking surface waves due to high magnitudes of momentum and mass transfer. Autonomous instruments can be challenging to deploy in this energetic zone. We are developing the Smartfin, a surfboard fin capable of measuring geolocated ocean chemistry...
Hydrothermal vent fluids play very important role in the deep-sea geochemistry cycle, and support the extreme biological communities. But, there are very few sensors can be used for the in situ measurement of the chemical compositions of the emerging vent fluids. The extremely high temperature and pressure will kill most of them. The traditional sampling technology cannot maintain the sample temperate...
