Forcing and Dynamics of Seafloor-Water Column Exchange on a Broad Continental Shelf
Forcing and Dynamics Seafloor-Water Column Exchange Broad Continental Shelf
2015/7/22
Relict sediments of elevated permeability characterize the majority of continental shelves globally (Emery, 1968). In these settings, interactions between benthic boundary layer (BBL) flows and seabed...
A Tabletop Demonstration of Atmospheric Dynamics:Baroclinic Instability
Tabletop Demonstration Atmospheric Dynamics Baroclinic Instability
2015/7/22
Here we study a fundamental instability mechanism of the atmosphere that affects us very directly in terms of mid-latitude winter weather. We provide a hands-on demonstration of this instability using...
Monitoring the Seafloor Using the Noninvasive Eddy Correlation Technique:Integrated Benthic Exchange Dynamics
Noninvasive Eddy Integrated Benthi Exchange Dynamics
2015/7/22
The eddy correlation technique has been used for 60 years in atmospheric boundary layer research to measure land-air exchanges of different constituents (e.g., Swinbank, 1951). Only recently, the tech...
Fundamentals of Geophysical Fluid Dynamics is a new textbook that provides an introduction to the basic dynamics governing fluid motion in a rotating system. This book is designed for first-year gradu...
Synthesis of Pacific Ocean Climate and Ecosystem Dynamics
The Pacific Ocean ecosystem climate research climate control Pacific Ocean ecosystem
2015/7/16
The goal of the Pacific Ocean Boundary Ecosystem and Climate Study (POBEX) was to diagnose the large-scale climate controls on regional transport dynamics and lower trophic marine ecosystem variabilit...
Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Advances in Marine Ecosystem Dynamics from US GLOBEC: The Horizontal-Advection Bottom-up Forcing Paradigm
Global ocean ecosystem dynamics ecosystem climate Marine ecosystems
2015/7/16
A primary focus of the US Global Ocean Ecosystem Dynamics (GLOBEC) program was to identify the mechanisms of ecosystem response to large-scale climate forcing under the assumption that bottom-up forci...
Cdrake: dynamics and transport of the Antarctic circumpolar current in drake passage
Antarctic circumpolar current dynamics and transport
2015/7/15
The Southern Ocean is especially sensitive to climate change, responding to
winds that have increased over the past 30 years (Thompson and Solomon,
2002) and warming at about one degree per centur...
Ocean Dynamics and the Carbon Cycle:Principles and Mechanisms
Ocean Dynamics Carbon Cycle Principles and Mechanisms
2015/7/15
Williams and Follows combined their expertise to write a book targeted at honors undergraduate or graduate students, as well as at professionals in ocean science who need to learn the fundamentals of ...
Sediment Dynamics Observed in the Jhoushuei River and Adjacent Coastal Zone in Taiwan Strait
Sediment Dynamics Observed Jhoushuei River Adjacent Coastal Zone Taiwan Strait
2015/7/13
Taiwan's rugged, mountainous terrain, a result of active tectonics, and its monsoonal climate create conditions that produce the greatest sediment yield compared to all land surfaces on Earth. It is e...
Dynamics of barotropic low-frequency fluctuations in San Francisco Bay during upwelling
Hydrodynamic modeling Low-frequency fluctuations San Francisco Bay
2015/6/30
Observations of wind, surface elevations, and currents in San Francisco Bay during the 1999 upwelling season are analyzed to understand the dynamics of low-frequency currents in upwelling-dominated es...
Seasonal dynamics of autotrophic and heterotrophic plankton metabolism and PCO2 in a subarctic Greenland fjord
Biological metabolic kinetics Greenland fjord
2014/10/16
We measured net planktonic community production (NCP), community respiration (CR), and gross primary
production (GPP) in September, February, and May in a subarctic Greenland fjord influenced by glac...
Biological- and physical-induced oxygen dynamics in melting sea ice of the Fram Strait
Biological- and physical-induced oxygen dynamics melting sea ice Fram Strait
2014/7/10
We investigated the production, consumption, and exchange of O2 in melting sea ice to assess the biological- and physical-induced O2 turnover. The underside of the ice was covered with 5–20 cm3 large,...
Nitrogen fixation and dissimilatory nitrate reduction to ammonium (DNRA) support nitrogen dynamics in Texas estuaries
Nitrogen fi xation dissimilatory nitrate
2014/4/30
We conducted continuous-flow experiments on intact sediment cores from Laguna Madre, Sabine Lake, East
Matagorda Bay, and Nueces Estuary to evaluate internal nitrogen (N) sources, sinks, and re...
Hydrogen peroxide dynamics in an agricultural headwater stream: Evidence for significant nonphotochemical production
Hydrogen peroxide dynamics nonphotochemical production
2014/4/2
Hydrogen peroxide (H2O2
) plays key roles in aquatic systems, including metal redox cycling and degradation
of organic matter into bioavailable forms. Abiotic photoproduction, via photo-oxidation of...
