Forcing and variability of nonstationary rip currents

Creator:: Long, J. W. and Özkan-Haller, H. Tuba
Abstract:: urface wave transformation and the resulting nearshore circulation along a section of coast with strong alongshore bathymetric gradients outside the surf zone are modeled for a consecutive 4 week time period. The modeled hydrodynamics are compared to in situ measurements of waves and currents collected during the Nearshore Canyon Experiment...

The great 2012 Arctic Ocean summer cyclone enhanced biological productivity on the shelves

Creator:: Zhang, Jinlun, Ashjian, Carin, Campbell, Robert, Hill, Victoria, Spitz, Yvette H., and Steele, Michael
Abstract:: A coupled biophysical model is used to examine the impact of the great Arctic cyclone of early August 2012 on the marine planktonic ecosystem in the Pacific sector of the Arctic Ocean (PSA). Model results indicate that the cyclone influences the marine planktonic ecosystem by enhancing productivity on the shelves...

Characterizing the circulation off the Kenyan-Tanzanian coast using an ocean model

Creator:: Mayorga-Adame, C. Gabriela, Strub, P. Ted, Batchelder, Harold P., and Spitz, Yvette H.
Abstract:: The Kenyan-Tanzanian coastal region in the western Indian Ocean faces several environmental challenges including coral reef conservation, fisheries management, coastal erosion, and nearshore pollution. The region lacks hydrodynamic records and oceanographic studies at adequate spatial and temporal scales to provide information relevant to the local environmental issues. We have developed...

The intertidal hydraulics of tide-dominated reef platforms

Creator:: Lowe, Ryan J., Leon, Arturo S., Symonds, Graham, Falter, James L., and Gruber, Renee
Abstract:: A 2 week field experiment investigated the hydrodynamics of a strongly tidally forced tropical intertidal reef platform in the Kimberley region of northwestern Australia, where the spring tidal range exceeds 8 m. At this site, the flat and wide (∼1.4 km) reef platform is located slightly above mean sea level,...

An assessment of phytoplankton primary productivity in the Arctic Ocean from satellite ocean color/in situ chlorophyll-a based models

Creator:: Lee, Younjoo J., Matrai, Patricia A., Friedrichs, Marjorie A. M., Saba, Vincent S., Antoine, David, Ardyna, Mathieu, Asanuma, Ichio, Babin, Marcel, Bélanger, Simon, Benoît‐Gagné, Maxime, Devred, Emmanuel, Fernández‐Méndez, Mar, Gentili, Bernard, Hirawake, Toru, Kang, Sung‐Ho, Kameda, Takahiko, Katlein, Christian, Lee, Sang H., Lee, Zhongping, Mélin, Frédéric, Scardi, Michele, Smyth, Tim J., Tang, Shilin, Turpie, Kevin R., Waters, Kirk J., and Westberry, Toby K.
Abstract:: We investigated 32 net primary productivity (NPP) models by assessing skills to reproduce integrated NPP in the Arctic Ocean. The models were provided with two sources each of surface chlorophyll-a concentration (chlorophyll), photosynthetically available radiation (PAR), sea surface temperature (SST), and mixed-layer depth (MLD). The models were most sensitive to...

Phenology of particle size distributions and primary productivity in the North Pacific subtropical gyre (Station ALOHA)

Creator:: White, Angelicque E., Letelier, Ricardo M., Whitmire, Amanda L., Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., and Karl, David M.
Abstract:: The particle size distribution (PSD) is a critical aspect of the oceanic ecosystem. Local variability in the PSD can be indicative of shifts in microbial community structure and reveal patterns in cell growth and loss. The PSD also plays a central role in particle export by influencing settling speed. Satellite-based...

Interannual variability of the subsurface eddy field in the Southeast Pacific

Creator:: Combes, Vincent, Hormazabal, Samuel, and Di Lorenzo, Emanuele
Abstract:: The Southeast Pacific, which encompasses the coasts of Peru and Chile, is one of the world's most productive regions resulting principally from the upwelling of subsurface nutrient-rich waters. Over the satellite altimetry era, there have been numerous evidence that surface mesoscale eddies play an important role in the offshore transport...

Distinguishing ichthyogenic turbulence from geophysical turbulence

Creator:: Pujiana, Kandaga, Moum, James N., Smyth, William D., and Warner, Sally J.
Abstract:: Measurements of currents and turbulence beneath a geostationary ship in the equatorial Indian Ocean during a period of weak surface forcing revealed unexpectedly strong turbulence beneath the surface mixed layer. Coincident with the turbulence was a marked reduction of the current speeds registered by shipboard Doppler current profilers, and an...

Particle distributions and dynamics in the euphotic zone of the North Pacific Subtropical Gyre

Creator:: Barone, Benedetto, Bidigare, Robert R., Church, Matthew J., Karl, David M., Letelier, Ricardo M., and White, Angelicque E.
Abstract:: During the summer of 2012, we used laser diffractometry to investigate the temporal and vertical variability of the particle size spectrum (1.25–100 µm in equivalent diameter) in the euphotic zone of the North Pacific Subtropical Gyre. Particles measured with this optical method accounted for ∼40% of the particulate carbon stocks...

Modeled ocean circulation in Nares Strait and its dependence on landfast-ice cover

Creator:: Shroyer, Emily L., Samelson, Roger M., Padman, Laurie, and Münchow, Andreas
Abstract:: Two simplified ocean simulations are used to study circulation and transport within Nares Strait. The simulations are similar, except that one included a coupled sea ice model that effectively established a landfast ice cover throughout the simulation year. Comparison between the ocean-only and ocean-ice simulations reveals a systematic change in...
