Ocean Mixing by Kelvin-Helmholtz Instability

Creator:: Smyth, William D. and Moum, James N.
Abstract:: Kelvin-Helmholtz (KH) instability, characterized by the distinctive finite-amplitude billows it generates, is an important mechanism in the development of turbulence in the stratified interior of the ocean. In particular, it is often assumed that the onset of turbulence in internal waves begins in this way. Clear recognition of the importance...

Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems

Creator:: Batchelder, Harold P., Daly, Kendra L., Davis, Cabell S., Ji, Rubao, Ohman, Mark D., Peterson, William T., and Runge, Jeffrey A.
Abstract:: 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 controls on zooplankton vital rates, especially the timing and magnitude of reproduction, growth, life-cycle progression, and mortality, determine species population dynamics, seasonal and spatial distributions,...

Observing biogeochemical cycles at global scales with profiling floats and gliders: Prospects for a global array

Creator:: Johnson, Kenneth S., Berelson, William M., Boss, Emmanuel S., Chase, Zanna, Claustre, Herve, Emerson, Steven R., Gruber, Nicolas, Kortzinger, Arne, Perry, Mary Jane, and Riser, Stephen C.
Abstract:: Chemical and biological sensor technologies have advanced rapidly in the past five years. Sensors that require low power and operate for multiple years are now available for oxygen, nitrate, and a variety of bio-optional properties that serve as proxies for important components of the carbon cycle (e.g., particulate organic carbon)....

Penguin Biogeography Along the West Antarctic Peninsula Testing the Canyon Hypothesis with Palmer LTER Observations

Creator:: Schofield, Oscar, Ducklow, Hugh, Bernard, Kim S., Doney, Scott, Patterson-Fraser, Donna, Gorman, Kristen, Martinson, Doug, Meredith, Michael, Saba, Grace, Stammerjohn, Sharon, Steinberg, Deborah, and Fraser, William
Abstract:: The West Antarctic Peninsula (WAP) is home to large breeding colonies of the ice-dependent Antarctic Adélie penguin (Pygoscelis adeliae). Although the entire inner continental shelf is highly productive, with abundant phytoplankton and krill populations, penguin colonies are distributed heterogeneously along the WAP (Ducklow et al., 2013, in this issue). This ecological...

Defining the word "Seamount"

Creator:: Staudigel, Hubert, Koppers, Anthony A. P., Lavelle, J. William, Pitcher, Tony J., and Shank, Timothy M.
Abstract:: Reading through this issue of Oceanography, it will become apparent that researchers in different disciplines see their seamounts in quite different ways. The term seamount has been defined many times (e.g., Menard, 1964; Wessel, 2001; Schmidt and Schmincke, 2000; Pitcher et al., 2007; International Hydrographic Organization, 2008; Wessel et al.,...

Synthesis of Pacific Ocean Climate and Ecosystem Dynamics

Creator:: Di Lorenzo, Emanuele, Combes, Vincent, Keister, Julie E., Strub, P. Ted, Thomas, Andrew C., Franks, Peter J. S., Ohman, Mark D., Furtado, Jason C., Bracco, Annalisa, Bograd, Steven J., Peterson, William T., Schwing, Franklin B., Chiba, Sanae, Taguchi, Bunmei, Hormazabal, Samuel, and Parada, Carolina
Abstract:: 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 variability in Pacific Ocean boundary systems. An international team of collaborators shared observational and eddy-resolving modeling data sets collected in the Northeast...

Volcanic Eruptions in the Deep Sea

Creator:: Rubin, Kenneth H., Soule, S. Adam, Chadwick, William W., Jr., Fornari, Daniel J., Clague, David A., Embley, Robert W., Baker, Edward T., Perfit, Michael R., Caress, David W., and Dziak, Robert P.
Abstract:: Volcanic eruptions are important events in Earth’s cycle of magma generation and crustal construction. Over durations of hours to years, eruptions produce new deposits of lava and/or fragmentary ejecta, transfer heat and magmatic volatiles from Earth’s interior to the overlying air or seawater, and significantly modify the landscape and perturb...

The Cascadia Initiative: A Sea Change In Seismological Studies of Subduction Zones

Creator:: Toomey, Douglas R., Allen, Richard M., Barclay, Andrew H., Dziak, Robert P., Tréhu, Anne M., Bell, Samuel W., Bromirski, Peter D., Carlson, Richard L., Chen, Xiaowei, Collins, John A., Evers, Brent, Forsyth, Donald W., Gerstoft, Peter, Hooft, Emilie E. E., Livelybrooks, Dean, Lodewyk, Jessica A., Luther, Douglass S., McGuire, Jeffrey J., Schwartz, Susan Y., Tolstoy, Maya, Weirathmueller, Michelle, and Wilcock, William S. D.
Abstract:: Increasing public awareness that the Cascadia subduction zone in the Pacific Northwest is capable of great earthquakes (magnitude 9 and greater) motivates the Cascadia Initiative, an ambitious onshore/offshore seismic and geodetic experiment that takes advantage of an amphibious array to study questions ranging from megathrust earthquakes, to volcanic arc structure,...

The Roles of Large Top Predators in Coastal Ecosystems: New Insights from long Term Ecological Research

Creator:: Rosenblatt, Adam E., Heithaus, Michael R., Mather, Martha E., Matich, Philip, Nifong, James C., Ripple, William J., and Silliman, Brian R.
Abstract:: Abstract: During recent human history, human activities such as overhunting and habitat destruction have severely impacted many large top predator populations around the world. Studies from a variety of ecosystems show that loss or diminishment of top predator populations can have serious consequences for population and community dynamics and ecosystem...

Applied Fisheries Oceanography: Ecosystem Indicators of Ocean Conditions Inform Fisheries Management in the California Current

Creator:: Peterson, William T., Fisher, Jennifer L., Peterson, Jay O., Morgan, Cheryl A., Burke, Brian J., and Fresh, Kurt L.
Abstract:: Fisheries oceanography is the study of ecological relationships between fishes and the dynamics of their marine environments and aims to characterize the physical, chemical, and biological factors that affect the recruitment and abundance of harvested species. A recent push within the fisheries management community is toward ecosystem-based management. Here, we...
