    • Finescale structure of the T-S relation in the eastern North Atlantic 

      Ferrari, Raffaele; Polzin, Kurt L. (American Meteorological Society, 2005-08)
      Distributions of temperature (T) and salinity (S) and their relationship in the oceans are the result of a balance between T–S variability generated at the surface by air–sea fluxes and its removal by molecular dissipation. ...
    • Finestructure and turbulence in the deep ocean 

      Hendricks, Peter J. (Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1977-01)
      Millimeter scale fluctuations in refractive index recorded with a freely sinking shadowgraph system are correlated with finestructure profiles of temperature, salinity and density and compared to models of ocean turbulence. ...
    • Finger puzzles 

      Schmitt, Raymond W. (Cambridge University Press, 2012-01-24)
      Salt fingers are a form of double-diffusive convection that can occur in a wide variety of fluid systems, ranging from stellar interiors and oceans to magma chambers. Their amplitude has long been difficult to quantify, ...
    • Finite difference modeling of geoacoustic interaction at anelastic seafloors 

      Stephen, Ralph A.; Swift, Stephen A. (Acoustical Society of America, 1994-01)
      A major problem in understanding seismic wave propagation in the seafloor is to distinguish between the loss of energy due to intrinsic attenuation and the loss of energy due to scattering from fine scale heterogeneities ...

      The article reports the first radiocarbon dating of a live African baobab (Adansonia digitata L.), by investigating wood samples collected from 2 inner cavities of the very large 2-stemmed Platland tree of South Africa. ...
    • Fire increases invasive spread of Molinia caerulea mainly through changes in demographic parameters 

      Jacquemyn, Hans; Brys, Rein; Neubert, Michael G. (Ecological Society of America, 2005-12)
      We investigated the effects of fire on population growth rate and invasive spread of the perennial tussock grass Molinia caerulea. During the last decades, this species has invaded heathland communities in Western Europe, ...
    • First autonomous bio-optical profiling float in the Gulf of Mexico reveals dynamic biogeochemistry in deep waters 

      Green, Rebecca E.; Bower, Amy S.; Lugo-Fernandez, Alexis (Public Library of Science, 2014-07-03)
      Profiling floats equipped with bio-optical sensors well complement ship-based and satellite ocean color measurements by providing highly-resolved time-series data on the vertical structure of biogeochemical processes in ...
    • First biological measurements of deep-sea corals from the Red Sea 

      Roder, C.; Berumen, Michael L.; Bouwmeester, J.; Papathanassiou, E.; Al-Suwailem, A.; Voolstra, Christian R. (Nature Publishing Group, 2013-10-03)
      It is usually assumed that metabolic constraints restrict deep-sea corals to cold-water habitats, with ‘deep-sea’ and ‘cold-water’ corals often used as synonymous. Here we report on the first measurements of biological ...
    • The First Law of Thermodynamics in a salty ocean 

      Warren, Bruce A. (2006-01-30)
      The First Law of Thermodynamics is developed from fundamentals for open, non-equilibrium systems of seawater in motion, exchanging salt and freshwater internally and with their surroundings, and varying continuously in ...
    • First observed wild birth and acoustic record of a possible infanticide attempt on a common bottlenose dolphin (Tursiops truncatus) 

      Perrtree, Robin M.; Sayigh, Laela S.; Williford, Allison; Bocconcelli, Alessandro; Curran, Mary C.; Cox, Tara M. (2015-06)
      We observed the birth of a common bottlenose dolphin (Tursiops truncatus) followed immediately by a possible infanticide attempt in the estuary near Savannah, Georgia. Our report is unique in several ways: first, we witnessed ...
    • Fish target strengths for use in echo integrator surveys 

      Foote, Kenneth G. (Acoustical Society of America, 1987-09)
      In situ measurements of fish target strength are selected for use in echo integrator surveys at 38 kHz. The results are expressed through equations in which the mean target strength TS is regressed on the mean fish length ...
    • FISH_ROCK : a tool for identifying and counting benthic organisms in bottom photographs 

      Ferrini, Vicki L.; Singh, Hanumant (Woods Hole Oceanographic Institution, 2006-01)
      Recent advances in underwater robotics and imaging technology now enable the rapid acquisition of large datasets of near-bottom high-resolution digital imagery. These images provide the potential for developing a non-invasive ...
    • Fishing for answers 

      Buesseler, Ken O. (2012-08-30)
      The triple disaster of the March 11, 2011, earthquake, tsunami, and subsequent radiation releases at Fukushima Dai-ichi were, and continue to be, unprecedented events for the ocean and for society. More than 80% of the ...
    • The five stable noble gases are sensitive unambiguous tracers of glacial meltwater 

      Loose, Brice; Jenkins, William J. (John Wiley & Sons, 2014-04-16)
      The five inert noble gases—He, Ne, Ar, Kr, and Xe—exhibit a unique dissolved gas saturation pattern resulting from the formation and addition of glacial meltwater to seawater. He and Ne become oversaturated, and Ar, Kr, ...
