The seasonal nitrogen cycle in Wilkinson Basin, Gulf of Maine, as estimated by 1-D biological model optimization
The objective of this study was to fit a simple ecosystem model to climatological nitrogen cycle data in the Gulf of Maine, in order to calibrate the biological model for use in future 3-D modelling studies. First ...
Handbook of oceanographic engineering materials : volume I - metals and alloys
(Woods Hole Oceanographic Institution, 1972-12)
This handbook is intended to serve as an aid in materials selection to Oceanographic engineers and designers. As such it is intentionally limited to materials that may be used advantageously in the marine environment.
Eddy-driven pulses of respiration in the Sargasso Sea
An analysis of nine years of data from the NW subtropical Atlantic reveals that variability in heterotrophic processes associated with (sub)mesoscale features has a major impact on the balance between photosynthesis and ...
Defining DNA-based operational taxonomic units for microbial-eukaryote ecology
DNA sequence information has been increasingly used in ecological research on microbial eukaryotes. Sequence-based approaches have included studies of the total diversity of selected ecosystems, the autecology of ...
Physically constrained maximum likelihood mode filtering
(Acoustical Society of America, 2010-04)
Mode filtering is most commonly implemented using the sampled mode shapes or pseudoinverse algorithms. Buck et al. [J. Acoust. Soc. Am. 103, 1813–1824 (1998)] placed these techniques in the context of a broader maximum a ...
Development and deployment of a precision underwater positioning system for in situ laser Raman spectroscopy in the deep ocean
The field of ocean geochemistry has recently been expanded to include in situ laser Raman spectroscopic measurements in the deep ocean. While this technique has proved to be successful for transparent targets, such as ...
Argo Development Program : final report
(Woods Hole Oceanographic Institution, 1986-06)
The purpose of the contract was to develop and place into operational status a new, combined research/inspection unmanned vehicle system called ARGO/JASON. ARGO is a high altitude search and survey vehicle for use in deep ...
Protocols for calibrating multibeam sonar
(Acoustical Society of America, 2005-04)
Development of protocols for calibrating multibeam sonar by means of the standard-target method is documented. Particular systems used in the development work included three that provide the water-column signals, namely ...
On the electromagnetic fields produced by marine frequency domain controlled sources
(John Wiley & Sons, 2009-10-14)
In recent years, marine controlled source electromagnetics (CSEM) has found increasing use in hydrocarbon exploration due to its ability to detect thin resistive zones beneath the seafloor. Although it must be recognized ...
High-frequency bistatic scattering by sub-bottom gas bubbles
(Acoustical Society of America, 1997-08)
A previous study of high-frequency acoustic backscattering data collected at Eckernfoerde Bay, Germany revealed that scattering is mainly due to methane gas bubbles buried about a meter beneath the seafloor [Tang et al., ...
