Acoustic Doppler Current Profilers and underwater gliders were simultaneously deployed as part of the Ocean Tracking Network to continuously monitor Halifax Line (HL) Nova Scotia (NSC) between 2008 2014. The HL transects Scotian Shelf, which connects dynamically important areas, such Grand Banks, Gulf Maine, St. Lawrence (GSL). oceanographic measurements made at during this period provide a unique opportunity study temperature, salinity, alongshore current conditions variability both...
Subtropical oceans contribute significantly to global primary production, but the fate of picophytoplankton that dominate in these low-nutrient regions is poorly understood. Working subtropical Mediterranean, we demonstrate subduction water at ocean fronts generates 3D intrusions with uncharacteristically high carbon, chlorophyll, and oxygen extend below sunlit photic zone into dark ocean. These contain fresh assemblages resemble photic-zone where originated. Intrusions propagate...
Abstract Within the international OneArgo program, a global array of autonomous profiling floats monitoring seawater properties, Deep-Argo mission aims to provide temperature, pressure, and salinity measurements down seabed with accuracy targets ±0.001°C, ±3 dbar, ±0.002, respectively. One Deep-Argo's main challenges is achieve this level accuracy. Three different CTDs are available for applications: extended-depth SBE41CP, SBE61 RBR argo |deep6k. We evaluated their performance at sea 4000...
Abstract The study of ocean dynamics and biophysical variability at submesoscales O (1) km h raises several observational challenges. To address these by underway sampling, we recently developed a towed profiler called the EcoCTD, capable concurrently measuring both hydrographic bio-optical properties such as oxygen, chlorophyll fluorescence, optical backscatter. EcoCTD presents an attractive alternative to currently used platforms due its light footprint, versatility in field, ease...
Abstract The static and dynamic performances of the RBR argo 3 are investigated using a combination laboratory-based in situ datasets from floats deployed as part an Argo pilot program. Temperature pressure measurements compare well to co-located reference data acquired shipboard CTDs. Static accuracy salinity is significantly improved 1) time lag for temperature, 2) quadratic dependence, 3) unit-based calibration each over its full range. Long-term deployments show no significant drift...
Abstract Export of Particulate Organic Carbon (POC) is mainly driven by gravitational sinking. Thus, traditionally, it thought that larger, faster‐sinking particles make up most the POC export flux. However, this need not be case for whose sinking speeds are comparable to vertical velocities a dynamic flow field can influence descent rate particles. Particles with different settling released in two process‐oriented model simulations an upper ocean eddying Northeast Pacific evaluate impact...

Abstract. Frontal zones within the Western Alboran Gyre (WAG) are characterized by a density gradient resulting from convergence of Atlantic and Mediterranean waters. Subduction along isopycnals at WAG periphery can play crucial role in upper ocean ventilation influences its stratification biogeochemical cycles. In 2019, physical parameters (comprising temperature, salinity, turbulent kinetic energy dissipation rates) data (oxygen chlorophyll-a) profiles were collected transects northern...
Abstract The focus of this study is on the relative roles winds and buoyancy in driving Nova Scotia Current (NSC) utilizing detailed hydrographic glider transects along Halifax Line. We define a Hydrographic Wind Index (HWI) using simplistic two‐layer model to represent NSC its frontal system. HWI based local characteristics density front extracted from data (e.g., slope). impact wind‐driven isopycnal tilting slope estimated corrected for accurately scale buoyancy‐driven component NSC....
Abstract This study demonstrates the long-term stability of salinity measurements from Argo floats equipped with inductive conductivity cells, which have extended float lifetimes as compared to electrode-type cells. New sensor payloads must meet demands governance committees before they are implemented globally. Currently, use CTDs cells designed and manufactured by RBR, Ltd., has been approved a Global Pilot. One requirement for new sensors is demonstrate stable over lifetime float. To...
