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...

A multiscale climate emulator for long-term morphodynamics (MUSCLE-morpho)

Creator:: Antolínez, José Antonio A., Méndez, Fernando J., Camus, Paula, Vitousek, Sean, González, E. Mauricio, Ruggiero, Peter, and Barnard, Patrick
Abstract:: Interest in understanding long-term coastal morphodynamics has recently increased as climate change impacts become perceptible and accelerated. Multiscale, behavior-oriented and process-based models, or hybrids of the two, are typically applied with deterministic approaches which require considerable computational effort. In order to reduce the computational cost of modeling large spatial and...

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...

Spring plankton dynamics in the Eastern Bering Sea, 1971-2050: Mechanisms of interannual variability diagnosed with a numerical model

Creator:: Banas, Neil S., Zhang, Jinlun, Campbell, Robert G., Sambrotto, Raymond N., Lomas, Michael W., Sherr, Evelyn, Sherr, Barry, Ashjian, Carin, Stoecker, Diane, and Lessard, Evelyn J.
Abstract:: A new planktonic ecosystem model was constructed for the Eastern Bering Sea based on observations from the 2007–2010 BEST/BSIERP (Bering Ecosystem Study/Bering Sea Integrated Ecosystem Research Program) field program. When run with forcing from a data-assimilative ice-ocean hindcast of 1971–2012, the model performs well against observations of spring bloom time...

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...

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...

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,...

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...

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...

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...
