We present three‐dimensional, high‐resolution simulations of ice melting at the calving face Store Glacier, a tidewater glacier in West Greenland, using Massachusetts Institute Technology general circulation model. compare simulated melt with an estimate derived from oceanographic data. The show turbulent upwelling and spreading freshwater‐laden plume along vigorous rates meters per day. August 2010 rate 2.0±0.3 m/d is within uncertainties 3.0±1.0 calculated Melting greatest depth, above...
The observed acceleration of ice shelf basal melt rates throughout West Antarctica could destabilize continental sheets and markedly increase global sea level. Explanations for decadal-scale intensification have focused on processes local to seas surrounding the shelves. A suite process-based model experiments, guided by CMIP6 forcing scenarios, show that freshwater from Antarctic Peninsula, propagated between marginal a coastal boundary current, causes enhanced melting Antarctica. anomaly...
This chapter presents the state of art concerning deep-sea Mediterranean environment: geology, hydrology, biology and fisheries. These are fields study dealt with in scientific papers this volume. The authors specialists who have addressed their research to environment during last years. introduction is an overview but not exhaustive review.
Abstract The wavenumber spectrum of sea surface height (SSH) is an important indicator the dynamics ocean interior. While SSH has been well studied at mesoscale wavelengths and longer, using both in situ oceanographic measurements satellite altimetry, it remains largely unknown for less than ~70 km. Surface Water Ocean Topography (SWOT) mission aims to resolve 15–150-km wavelengths, which specified as one requirements. calibration validation (CalVal) requires ground truth a synoptic field...
Estimates of the kinetic energy transfer from wind to ocean are often limited by spatial and temporal resolution surface currents winds. Here we examine work in a pair global, very high-resolution (1/48° 1/24°) MIT general circulation model simulations Latitude-Longitude-polar Cap (LLC) configuration that provide hourly output at resolutions few kilometers include tidal forcing. A cospectrum analysis stress shows positive contribution large scales (>300 km) near-inertial frequency negative...
Abstract Enhanced vertical velocities associated with submesoscale motions may rapidly modify mixed layer depths and increase exchange between the ocean interior. These dynamics are of particular importance in Southern Ocean, where ventilation many density classes occurs. Here we present results from an observational field program southern Drake Passage, a region preconditioned for instability owing to its strong mesoscale eddy field, persistent fronts, down-front winds, weak stratification....
Abstract West Antarctic ice shelves have thinned dramatically over recent decades. Oceanographic measurements that explore connections between offshore warming and transport across a continental shelf with variable bathymetry toward are needed to constrain future changes in melt rates. Six years of seal‐acquired observations provide extensive hydrographic coverage the Bellingshausen Sea, where ship‐based scarce. Warm but modified Circumpolar Deep Water floods establishes cyclonic circulation...
Abstract The area west of the Kerguelen Islands (20–70°E/45–60°S) is characterized by a weak mesoscale activity except for standing meander region Antarctic Circumpolar Current (ACC) localized between 20 and 40°E. A unique bio-physical dataset at high-resolution collected southern elephant seal ( Mirounga leonina ) reveals conspicuous increase in foraging site up to 5 times larger than during rest her three-month trip Islands. Here, we propose physical explanation such high biological based...
Marine and atmospheric parameters, including temperature observations from surface to 80 m (at 6 depths) are measured since September 1973 on a higher-than-weekly frequency, at coastal station 4 km offshore L'Estartit (Costa Brava; NW Mediterranean). This constitutes the longest available uninterrupted oceanographic time series in Mediterranean Sea. The present contribution focuses observed climatic trends (°C/year) of air (AT; 0.05), sea (SST; 0.03), depth (S80T; 0.02) level (SL; 3.1...
Abstract The structure of the Antarctic Slope Front (ASF) and associated Current (ASC) on Scotia Sea side Weddell‐Scotia Confluence (WSC) is described using data from a hydrographic survey three 1 year long moorings across continental slope. ASC in this region flows westward along isobaths with an annual mean speed ∼0.2 m s −1 , time variability dominated by K O tidal diurnal constituents, narrowband oscillation ∼2‐week period attributable to spring/neap cycle, seasonal variability....
Abstract On behalf of our ocean community authors and readers, the editors at JGR‐Oceans would like to sincerely thank all those who gave their valuable time review manuscripts for journal in 2024. Thank YOU!
The circulation in Blanes canyon, an interruption the NW Mediterranean continental shelf north of Barcelona, was investigated. study employs data from oceanographic surveys carried out summer and fall 2003. Velocity show that vicinity break flow is deflected along canyon walls. A cyclonic mean can be seen over mouth owing to vortex stretching fluid parcels advected across break. Field observations are qualitative agreement with fundamental dynamic considerations based on potential vorticity...

It important for mantle flow, oceanographic water masses, migrations biota.
