  • Ice Draft Anomalies Document the Deterioration of Beaufort Gyre Perennial Sea Ice

    Ice Draft Anomalies Document the Deterioration of Beaufort Gyre Perennial Sea Ice

    Top: Annual cycles of decadal mean sea ice drafts are computed from moored sonar data at 4 locations in the Beaufort Gyre, Arctic Ocean. Bottom: Removing the annual cycles reveal monthly anomaly time series at each mooring. These show that sea ice in the western Arctic basin became thinner and largely homogenous after 2007.

  • Wave Focusing and Underwater Light Geometry in Upper Ocean

    Wave Focusing and Underwater Light Geometry in Upper Ocean

    The sea surface waves (in blue) act as optical lenses and bundles of incident rays (in magenta) are converged to visual focal points under wave crests and are diverged beneath wave troughs. The resulting underwater light field is dynamic and evolving as waves pass by.

  • A Curious Local Surface Salinity Maximum in the Northwestern Tropical Atlantic

    A Curious Local Surface Salinity Maximum in the Northwestern Tropical Atlantic

    Aquarius SSS climatology, surface drifter currents, and TRMM rainfall (6mm/day contour). Tropical salinity maximum starts developing in boreal winter when Amazon discharge is minimal, but the NBC retroflection is still present. Salty water advection produces the salty signature of the western NECC sector in contrast to the fresh signature present in summer – early fall.

  • Observations of Near-field River Plume Turbulence from an AUV

    Observations of Near-field River Plume Turbulence from an AUV

    Profiles through the Merrimack River plume showing turbulent kinetic energy dissipation rate, (colorbar in units of log10 [m2s-3]) from overturn scaling (top), and velocity microstructure (bottom). Both panels are overlain by density contours and the yo-yo path of the T-REMUS vehicle. Intense turbulence is seen near liftoff (1000 – 2000 m) in both cases, decreasing seaward.

  • Updraft Event Lifts Particulates to Mid-water Column Over the Continental Shelf

    Updraft Event Lifts Particulates to Mid-water Column Over the Continental Shelf

    8-hour record of (a) water-column measurements from southern Monterey Bay, California (70-m depth), October 2011, showing (b) supercritical (hydraulic jump) conditions during a high-amplitude internal tide, followed by (c) strong vertical updraft velocities and (a) the subsequent appearance of a layer of suspended particulates well above the seafloor.

  • A Schematic Diagram of Each of the Heat Fluxes Within the Context of a Tidal Flat

    A Schematic Diagram of Each of the Heat Fluxes Within the Context of a Tidal Flat

    Schematic diagram of heat fluxes on tidal flats. Arrows indicate direction of heat flux. See section 2.2.3 for a description of the various terms.

  • Submesoscale Horizontal Eddy Diffusivities from in-situ Observations Across an Ocean Front

    Submesoscale Horizontal Eddy Diffusivities from in-situ Observations Across an Ocean Front

    The front position was identified in the Northwestern Mediterranean (a) by in-situ Lagrangian Coherent Structures from dispersion patterns of Lagrangian drifters (b) and AVHRR imagery (c). Eddy diffusivity was computed combining cross-front widths from thermosalinograph sections with strain rates from drifter trajectories (d). The estimates are log-normally distributed with 70% of values within 0.4-5 m2s-1 (e).
