Seasonal renewal of the California Current: The spring transition off California

Creator:: Lynn, Ronald J., Bograd, Steven J., Chereskin, Teresa K., and Huyer, Adriana, 1945-
Abstract:: A pair of high-resolution oceanographic surveys in March and April 1995 revealed a large and rapid transition from late winter to spring conditions in the coastal zone off central and southern California. These data are unique in capturing the detailed three-dimensional physical structure of and biological response to the spring...

Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:: Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.
Abstract:: Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...

Spatial and temporal variability of freshwater discharge into the Gulf of Alaska

Creator:: Hill, D. F., Bruhis, N., Calos, S. E., Arendt, A., and Beamer, J.
Abstract:: A study of the freshwater discharge into the Gulf of Alaska (GOA) has been carried out. Using available streamgage data, regression equations were developed for monthly flows. These equations express discharge as a function of basin physical characteristics such as area, mean elevation, and land cover, and of basin meteorological...

On the dynamics of the Zanzibar Channel

Creator:: Zavala-Garay, J., Theiss, J., Moulton, M., Walsh, C., van Woesik, R., Mayorga-Adame, C. G., García‐Reyes, M., Mukaka, D. S., Whilden, K., and Shaghude, Y. W.
Abstract:: The Zanzibar Channel lies between the mainland of Tanzania and Zanzibar Island in the tropical western Indian Ocean, is about 100 km long, 40 km wide, and 40 m deep, and is essential to local socioeconomic activities. This paper presents a model of the seasonal and tidal dynamics of the...

Poleward propagating subinertial alongshore surface currents off the U.S. West Coast

Creator:: Kim, Sung Yong, Cornuelle, Bruce D., Terrill, Eric J., Jones, Burt, Washburn, Libe, Moline, Mark A., Paduan, Jeffrey D., Garfield, Newell, Largier, John L., Crawford, Greg, and Kosro, P. Michael
Abstract:: The network comprising 61 high-frequency radar systems along the U.S. West Coast (USWC) provides a unique, high resolution, and broad scale view of ocean surface circulation. Subinertial alongshore surface currents show poleward propagating signals with phase speeds of O(10) and O(100–300) km d⁻¹ that are consistent with historical in situ...

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...

Structure and dynamics of the Columbia River tidal plume front

Creator:: Kilcher, Levi F. and Nash, Jonathan D.
Abstract:: Time‐dependent buoyant plumes form at the outflow of tidally dominated estuaries. When estuary discharge velocity exceeds plume internal wave speed c, a sharp front forms at the plume’s leading edge that expands from the time‐dependent source. Using observations of the Columbia River tidal plume from multiple tidal cycles we characterize...

A new method for estimating the turbulent heat flux at the bottom of the daily mixed layer

Creator:: Imawaki, Shiro, Niiler, Pearn P., Gautier, Catherine H., Halpern, David, Knox, Robert A., Large, William G., Luther, Douglas S., McWilliams, James C., Moum, James N., and Paulson, Clayton A.
Abstract:: A new method is presented for estimating the vertical turbulent heat flux at the bottom of the daily mixed layer from the temperature data in the mixed layer and net solar irradiance data at the sea surface. We assume that fluctuations in the divergence of advective heat flux have longer...

Intrathermocline eddies in the coastal transition zone off central Chile (31–41°S)

Creator:: Hormazabal, Samuel, Combes, Vincent, Morales, Carmen E., Correa-Ramirez, Marco A., Di Lorenzo, Emmanuel, and Nuñez, Sergio
Abstract:: The three-dimensional structure and the origin of mesoscale anticyclonic intrathermocline eddies (ITEs) in the coastal transition zone (CTZ) off central Chile (31–41°S) were analyzed through the combination of data from oceanographic cruises and satellite altimetry, and the application of an eddy-resolving primitive equation ocean model coupled with a numerical experiment...

Semidiurnal internal tide in JASIN: Observations and simulation

Creator:: deWitt, L. M., Levine, Murray D., Paulson, C. A., and Burt, W. V.
Abstract:: Temperature was observed in the upper 80 m by moored thermistor chains at three locations in Rockall Channel west of Scotland. Isotherms were interpolated, and a 1‐week period of exceptionally energetic tidal oscillations was analyzed. The moored array (horizontal separations ranging from 6 to 20 km) was used as an...
