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...
Carl Wunsch has written a compelling and important editorial in Science (15 Jan 93, p. 296–297), "Marine Sciences in the Coming Decades," which is based on a 1992 study by the Ocean Studies Board of t...
The Application of Video Image Processing to the Study of Nearshore Processes
Nearshore Processes Video Image
2015/8/19
Perhaps the most popular oceanographic setting for the public is the beach and nearshore environment. Poetic accounts since early history describe the comings and goings of tides, waves and sand. More...
Larval Transport and Coastal Upwelling: An Application of HF Radar in Ecological Research
Larval Transport Coastal Upwelling HF Radar Ecological Research
2015/8/10
For many marine fish and invertebrate species, near-surface currents strongly affect the likelihood of surviving as a planktonic larva and arriving at a suitable location, say, a rocky coastline, a ke...
The Navy's Application of Ocean Forecasting to Decision Support
Navy's Application Ocean Forecasting Decision Support
2015/7/20
The Naval Oceanographic Office (NAVOCEANO) provides daily operational global, regional, and coastal ocean model forecasts and their associated prediction products. The models utilized include three-di...
Numerical diffusion for flow-aligned unstructured grids with application to estuarine modeling
unstructured grid numerical diffusion grid generation grid alignment
2015/6/30
The benefits of unstructured grids in hydrodynamic models are well understood but in many cases lead to greater numerical diffusion compared with methods available on structured grids. The flexible na...
Precise determination of Sr/Ca by laser ablation ICP-MS compared to ICP-AES and application to multi-century temperate corals
coral Sr/Ca laser ablation ICP-MS ICP-AES
2017/4/11
Coral skeletal Sr/Ca compositions are valuable tools for the reconstruction of past tropical climate. While solutionbased
ICP-AES has become the preferred method to obtain monthly-resolved Sr/Ca reco...

Marine renewable energy high waves tidal power energy density the ocean thermal power generation
2015/7/7
Marine renewable energy has many attractive qualities, including high energy densities for ocean wave and tidal power generation, and a high capacity factor for ocean thermal power generation. However...
The isotopic and hydrologic response of small, closed-basin lakes to climate forcing from predictive models: Application to paleoclimate studies in the upper Columbia River basin
isotopic hydrologic closed-basin
2014/4/17
Simulations conducted using a coupled lake-catchment, hydrologic and isotope mass-balance model indicate
that small, closed-basin lakes in north-central Washington are isotopically sensitive to chang...
Application of Empirical Mode Energy to the Analysis of Fluctuating Signals
empirical mode decomposition energy feature extraction fluctuant signal analysis
2011/9/9
After an aerial object enters the water, physical changes to sounds in the water caused by the accompanying bubbles are quite complex. As a result, traditional signal analyzing methods cannot identify...
Lagrangian drifter paths and length scales in the tropical Pacific warm pool from 1990 to 1991:with application of fractal techniques
Lagrangian drifter paths length scales tropical Pacific warm pool fractal techniques
2009/11/16
This paper presents an analysis of WOCE/TOGA surface drifter paths and its interpretation in conjunction with the west Pacific warm pool water motion. Our interest here lies in the existence of scale ...
Ensemble Kalman filter assimilation of temperature and altimeter data with bias correction and application to seasonal prediction
Kalman filter assimilation temperature and altimeter data bias correction and application seasonal prediction
2009/11/9
To compensate for a poorly known geoid, satellite altimeter data is usually analyzed in terms of anomalies from the time mean record. When such anomalies are assimilated into an ocean model, the bias ...
