New Application Acoustics Marine Life Populations
2018/2/1
Researchers at Scripps Institution of Oceanography at the University of California San Diego were part of an international team that for the first time used hydroacoustics as a method for comparing th...
USING ISOLATION BY DISTANCE AND EFFECTIVE DENSITY TO ESTIMATE DISPERSAL SCALES IN ANEMONEFISH
Amphiprion clarkii continuous population
2015/12/11
Robust estimates of dispersal are critical for understanding population dynamics and local adaptation, as well as for successful
spatial management. Genetic isolation by distance patterns hold clues ...
Temperature- and cholesterol-induced changes in eicosapentaenoic acid limitation of Daphnia magnadetermined by a promising method to estimate growth saturation thresholds
Temperature cholesterol-induced changes in eicosapentaenoic acid limitation Daphnia magnadetermined a promising method estimate growth saturation thresholds
2014/4/8
We present data on eicosapentaenoic acid (EPA)-limited growth responses ofDaphnia magnaunder different temperatures and different dietary cholesterol availabilities to assess how EPA growth saturation...
Comparative estimate of P fluxes in lakes: A comment on ‘‘Fish decomposition in boreal lakes and biogeochemical implications’’ by Chidami and Amyot (2008)
Comparative estimate P fluxes in lakes Fish decomposition in boreal lakes biogeochemical implications Chidami Amyot
2014/4/16
The contribution of fish and their relative importance in the nutrient dynamics of lakes (sink vs. source) continue to be a topic of debate (Mehner et al. 2007; Wurtsbaugh 2007; Sereda et al. 2008b). ...
Response to ‘‘Comparative estimate of P fluxes in lakes’’ by J. M. Sereda and J. J. Hudson
Comparative estimate of P fluxes in lakes J. M. Sereda J. J. Hudson
2014/4/16
Sereda and Hudson (2010) are commenting on a carcassbound phosphorus (P) flux estimate reported in an article by Chidami and Amyot (2008). This article mainly presents in situ experimental evidence on...
Using a linear array to estimate the velocity of underwater moving targets
underwater velocity measurement linear array direction of arrival (DOA) deterministic maximum likelihood signal phase matching
2011/9/13
A new method uses a linear array that takes advantage of underwater physical sound fields to estimate the velocity of an underwater moving target. The mathematical model was established by considering...

Annual Poleward Energy Northern Hemisphere Oceans
2009/4/2
Recent measurements of the earth's radiation budget from satellites, together with extensive atmospheric energy transport summaries based on rawinsonde data, allow a new estimate of the required polew...
The Fraction of Vertical Isotherm Deflections Associated with Eddies：An Estimate from Multiship XBT Surveys
Vertical Isotherm Deflections Eddies Multiship XBT Surveys
2009/2/16
Six multiship XBT surveys in the area between 29 and 42°N in the North Pacific and North Atlantic Oceans were examined with respect to the following questions: What fraction of significant vertical is...
An Estimate of Equatorial Upwelling in the Pacific
Equatorial Upwelling the Pacific cool water
2009/2/10
Upwelling in the equatorial Pacific Ocean manifests itself by a tongue of cool water stretching from the Galapagos Islands to the date line. To estimate the rate of upwelling, the mass, heat and salt ...

North Atlantic Circulation Finite-Difference Model
2008/12/18
A finite-difference model of the North Atlantic is constructed for the purpose Of making an estimate of the circulation through an inverse calculation. The database is eclectic, and includes hydrograp...
A Basinwide Estimate of Vertical Mixing in the Upper Pycnocline: Spreading of Bomb Tritium in the North Pacific Ocean
Basinwide Estimate Vertical Mixing Upper Pycnocline Bomb Tritium North Pacific Ocean
2008/7/21
The vertical diffusivity KV in the upper half-kilometer of the North Pacific subtropical pycnocline is estimated from observations of the spreading rate of anthropogenic tritium. The calculation is ba...

Ring Separations Loop Current Gulf of Mexico
2008/7/1
The most energetic events in the circulation of the Gulf of Mexico are the separation of large anticyclonic rings from the Loop Current. Building on previous work, the authors examine all the apparent...
