Finite element simulation of broadband biosonar signal propagation in the near- and far-field of an echolocating Atlantic bottlenose dolphin (Tursiops truncatus)
(Acoustical Society of America, 2018-05-02)Bottlenose dolphins project broadband echolocation signals for detecting and locating prey and predators, and for spatial orientation. There are many unknowns concerning the specifics of biosonar signal production and ... -
Changes in species abundance after seven years of elevated atmospheric CO2 and warming in a Subarctic birch forest understorey, as modified by rodent and moth outbreaks
(PeerJ, 2018-05-29)A seven-year long, two-factorial experiment using elevated temperatures (5 °C) and CO2 (concentration doubled compared to ambient conditions) designed to test the effects of global climate change on plant community composition ... -
The origin and role of organic matrix in coral calcification: insights from comparing coral skeleton and abiogenic aragonite
(Frontiers Media, 2018-05-15)Understanding the mechanisms of coral calcification is critical for accurately projecting coral reef futures under ocean acidification and warming. Recent suggestions that calcification is primarily controlled by organic ... -
Characterizing the duration and severity of fishing gear entanglement on a North Atlantic right whale (Eubalaena glacialis) using stable isotopes, steroid and thyroid hormones in baleen
(Frontiers Media, 2018-05-15)North Atlantic right whales (Eubalaena glacialis) are highly endangered and frequently exposed to a myriad of human activities and stressors in their industrialized habitat. Entanglements in fixed fishing gear represent a ... -
Photochemical oxidation of oil reduced the effectiveness of aerial dispersants applied in response to the Deepwater Horizon spill
(American Chemical Society, 2018-04-25)Chemical dispersants are one of many tools used to mitigate the overall environmental impact of oil spills. In principle, dispersants break up floating oil into small droplets that disperse into the water column where they ... -
The Ra-226–Ba relationship in the North Atlantic during GEOTRACES-GA01
(Copernicus Publications on behalf of the European Geosciences Union, 2018-05-17)We report detailed sections of radium-226 (226Ra, T1∕2 = 1602 years) activities and barium (Ba) concentrations determined in the North Atlantic (Portugal–Greenland–Canada) in the framework of the international GEOTRACES ... -
Cohesive and mixed sediment in the Regional Ocean Modeling System (ROMS v3.6) implemented in the Coupled Ocean–Atmosphere–Wave–Sediment Transport Modeling System (COAWST r1234)
(Copernicus Publications on behalf of the European Geosciences Union, 2018-05-14)We describe and demonstrate algorithms for treating cohesive and mixed sediment that have been added to the Regional Ocean Modeling System (ROMS version 3.6), as implemented in the Coupled Ocean–Atmosphere–Wave–Sediment ... -
Climate variability, volcanic forcing, and last millennium hydroclimate extremes
(American Meteorological Society, 2018-05-03)Multidecadal hydroclimate variability has been expressed as “megadroughts” (dry periods more severe and prolonged than observed over the twentieth century) and corresponding “megapluvial” wet periods in many regions around ... -
Coincident mass occurrence of gelatinous zooplankton in northern Norway
(Frontiers Media, 2018-05-23)In autumn 2015, several sources reported observations of large amounts of gelatinous material in a large north Norwegian fjord system, either caught when trawling for other organisms or fouling fishing gear. The responsible ... -
The design and construction of a towed multi-port water sampling probe for 100 meter depths
(Woods Hole Oceanographic Institution, 1980-05)The experimental towed multi-port water sampler was designed to provide a shipboard science party with the capability of obtaining continuous water samples from the surface to a 100 meter depth. The device will ... -
Archived time-series of Atlantic Ocean meteorological variables and surface fluxes
(Woods Hole Oceanographic Institution, 1979-01)Time-series of monthly averages of latent, sensible and radiational heat fluxes and momentum fluxes at the surfaces of the North and South Atlantic Oceans were calculated from ship weather observations. These fluxes, ... -
Free drifting buoy trajectories in the Gulf Stream system : 1975-1978 : a data report
(Woods Hole Oceanographic Institution, 1979-01)From 1975 to 1978, thirty-one satellite-tracked free-drifting surface buoys were launched in the Gulf Stream system. Most of these buoys were launched in cyclonic rings, as part of an interdisciplinary Gulf Stream ... -
Some evidence for boundary mixing in the deep ocean
(Woods Hole Oceanographic Institution, 1979-01)Profiles of salinity and potential temperature in the deep ocean are presented which suggest the characteristic signature of two complementary mixing processes: vertical mixing within ~50-m-thick layers at boundaries and ... -
A seismic refraction experiment in the central Banda Sea
(Woods Hole Oceanographic Institution, 1979-02)A seismic refraction experiment in the central Banda Sea is interpreted by using both slope intercept and delay time function methods. The crustal structure is shown to be oceanic, with velocities (4.97, 6.47, 7.18, and ... -
Observations of energetic low frequency current fluctuations in the Charlie-Gibbs fracture zone
(Woods Hole Oceanographic Institution, 1979-02)Relatively energetic low frequency fluctuations in horizontal currents are found to exist below the thermocline in the northern trough of the Charlie-Gibbs Fracture Zone. For example, deep eddy kinetic energy levels there ... -
A census of Gulf Stream rings, spring 1975
(Woods Hole Oceanographic Institution, 1979-02)During 1975 several shipboard expendable bathythermograph surveys plus satellite infrared imagery provided a nearly synoptic view of the distribution and number of Gulf Stream rings in the western North Atlantic. Twelve ... -
HMMoce : an R package for improved geolocation of archival-tagged fishes using a hidden Markov method
(2017-11)Electronic tagging of marine fishes is commonly achieved with archival tags that rely on light levels and sea surface temperatures to retrospectively estimate movements. However, methodological issues associated with ... -
Gas chromatography-mass spectrometry facility : recent improvements and applications
