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...

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...

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)....

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...

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...

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...

The New Age of Hyperspectral Oceanography

Creator:: Chang, Grace, Mahoney, Kevin, Briggs-Whitmire, Amanda, Kohler, David, Mobley, Curtis, Lewis, Marlon, Moline, Mark, Boss, Emmanuel, Kim, Minsu, Philpot, William, and Dickey, Tommy
Abstract:: A multispectral optical sensor collects data at select wavebands or channels. An example is the Sea-viewing Wide-Field-of-view Sensor (SeaWiFS) ocean color satellite, which measures eight wavebands between 402 and 885 nm (20-40 nm bandwidth with peaks centered around 412, 443, 490, 510, 555, 670, 765, and 865 nm). Optical oceanographers...

Eruption of South Sarigan Seamount, Northern Mariana Islands: Insights into Hazards from Submarine Volcanic Eruptions

Creator:: Embley, Robert W., Tamura, Yoshihiko, Merle, Susan G., Sato, Tomoki, Ishizuka, Osamu, Chadwick, William W. Jr., Wiens, Douglas A., Shore, Patrick, and Stern, Robert J.
Abstract:: The eruption of South Sarigan Seamount in the southern Mariana arc in May 2010 is a reminder of how little we know about the hazards associated with submarine explosive eruptions or how to predict these types of eruptions. Monitored by local seismometers and distant hydrophones, the eruption from ~ 200...

Jellyfish, Forage Fish, and the World’s Major Fisheries

Creator:: Robinson, Kelly L., Ruzicka, James J., Decker, Mary Beth, Brodeur, Richard D., Hernandez, Frank J., Quiñones, Javier, Acha, E. Marcelo, Uye, Shin-ichi, Mianzan, Hermes, and Graham, William M.
Abstract:: A majority of the world’s largest net-based fisheries target planktivorous forage fish that serve as a critical trophic link between the plankton and upper-level consumers such as large predatory fishes, seabirds, and marine mammals. Because the plankton production that drives forage fish also drives jellyfish production, these taxa often overlap...

Bottom Characterization from Hyperspectral Image Data

Abstract:: In optically shallow waters, i.e., when the bottom is visible through the water, a tantalizing variety and level of detail about bottom characteristics are apparent in aerial imagery (Figure 1a). Some information is relatively easy to extract from true color, 3-band imagery (e.g., the presence and extent of submerged vegetation),...
