Ocean State Estimation and Prediction in Support of Oceanographic Research
Estimation and Prediction Oceanographic Researc
2015/8/5
The ocean is changing vigorously on a wide range of time and space scales. This variability leads to substantial problems in observing and modeling (simulating) the rapidly changing flow field, the oc...

Ocean Science Education Combines Traditional
2015/7/29
Sea Education Association (SEA), located in Woods Hole, Massachusetts, offers introductory oceanographic instruction in the classroom and hands-on research training at sea to create a unique education...
Monitoring Approaches for Early Warning of Domoic Acid Events in Washington State
Monitoring Approaches Early Warning Domoic Acid Events Washington State
2015/7/27
On the U.S. west coast, blooms of the potentially toxic diatom Pseudo-nitzschia can cause amnesic shellfish poisoning (ASP), resulting in economic impacts to coastal economies and public health concer...
As one of few who have been involved in the equation of state of seawater over the last 40 years, I was invited to review some of the history behind its early development and also the more recent ther...
Spurred by the development of satellite and in situ observing systems, global ocean state estimation has flourished in the past decade. Today, a suite of global ocean state estimates has been generate...
The relative importance of heterotrophic bacteria to pelagic ecosystem dynamics varies with reservoir trophic state
heterotrophic bacteria pelagic ecosystem dynamics varies reservoir trophic state
2014/4/17
We tested the hypothesis that nutrient sequestration and carbon flow through heterotrophic bacteria is relatively highest in oligotrophic systems and decreases with trophic state in 17 reservoirs in T...
Characteristics and sources of chromophoric dissolved organic matter in lakes of the Yungui Plateau, China, differing in trophic state and altitude
Characteristics sources of chromophoric dissolved
2014/4/17
The high-mountain lakes on the Yungui Plateau in China are exposed to high-intensity ultraviolet radiation, and
contain low concentrations of chromophoric dissolved organic matter (CDOM). We determin...
Hemoglobin concentration in Daphnia (D. galeata-hyalina) from the epilimnion is related to the state of nutrition and the degree of protein homeostasis
Daphnia protein homeostasis
2014/4/16
The function of hemoglobin (Hb), which is a key protein of many species, was analyzed in Daphnia from the
field. Temperature and oxygen content; abundance and composition of phytoplankton; and abunda...

A fractal model for the sea state bias in radar altimetry
fractal model sea state bias radar altimetry
2009/11/13
The Kirchhoff approximation is used to determine the sea state bias in radar altimetry. A weakly nonlinear model of the sea waves is used to derive the joint moments of two different points separated ...
Death by dissolution: Sediment saturation state as a mortality factor for juvenile bivalves
Sediment saturation state juvenile bivalves
2014/4/18
We show that death by dissolution is an important size-dependent mortality factor for juvenile bivalves.
Utilizing a new experimental design, we were able to replicate saturation states in sediments ...
An ecological study of a massive bloom of toxigenic Pseudo-nitzschia cuspidata off the Washington State coast
massive bloom of toxigenic Pseudo-nitzschia
2014/4/17
In September 2004 a large, nearly monospecific diatom bloom of Pseudo-nitzschia cuspidata off the coast of the
state of Washington reached cell concentrations of 6.1 3 106
cells L21
and produced ma...
Numerical Simulation Studies of Oceanic Anomalies in the North Pacific Basin. I：The Ocean Model and the Long-Term Mean State
Oceanic Anomalies North Pacific Basin Long-Term Mean State
2009/2/23
A three-dimensional, prognostic numerical model of the North Pacific Ocean, possessing an actual coastal configuration and ten layers (but constant depth), has been developed in order to show the phys...
Steady-State Diagnostic Model of the New York Bight
Steady-State Diagnostic Model New York Bight
2009/2/19
A qualitative evaluation is made of the output from a finite-element, steady-state diagnostic model to observed time-averaged currents. The model uses a vorticity balance equation with linear bottom f...

Steady-State Energy Balance Short Gravity Wave Systems
2009/2/18
Steady-state energy balances of short gravity wave systems generated in a wave tank with and without airflow have been measured and compared with the predictions of perturbation theory. Wind-wave spec...
