The Costa Rica Dome : a study of physics, zooplankton and blue whales

Creator:: Matteson, Robyn S.
Abstract:: At the Costa Rica Dome (CRD), upwelling associated with cyclonic circulation and the presence of a shallow thermocline support a highly productive biological habitat, exploited by marine fauna at several trophic levels. During January 2008, a cruise to the CRD by the R/V Pacific Storm was conducted to relocate blue...

Zooplankton of the Galapagos Islands

Creator:: Figueroa, Diego
Abstract:: The marine climate of the Galapagos is spatially and seasonally heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has never been done. This study is an initial effort to establish the distribution and community structure of zooplankton in the Archipelago. I collected zooplankton samples by vertical tows over the Galapagos...

Seamount subduction and earthquakes

Creator:: Watts, Anthony B., Koppers, Anthony A. P., and Robinson, David P.
Abstract:: Seamounts are ubiquitous features of the seafloor that form part of the fabric of oceanic crust. When a seamount enters a subduction zone, it has a major affect on forearc morphology, the uplift history of the island arc, and the structure of the downgoing slab. It is not known, however,...

Subseasonal SST Variability in the Tropical Eastern North Pacific during Boreal Summer

Creator:: Maloney, Eric D., Chelton, Dudley B., and Esbensen, Steven K.
Abstract:: Boreal summer intraseasonal (30–90-day time scale) sea surface temperature (SST) variability in the east Pacific warm pool is examined using Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI) sea surface temperatures during 1998–2005. Intraseasonal SST variance maximizes at two locations in the warm pool: in the vicinity of 9°N, 92°W...

Increased dissolved terrestrial input to the coastal ocean during the last deglaciation

Creator:: Klinkhammer, Gary P., Mix, Alan C., and Haley, B. A.
Abstract:: Here we present the first downcore results for a new paleoproxy, the Mn/Ca ratio of foraminiferal calcite, applied to sediment accumulated in the extreme Eastern Tropical North Pacific (ETNP) over the last 30,000 years. The Mn/Ca results are compared to oxygen isotopes and sea surface temperature calculated from Mg/Ca. We...

Seawater intrusion through the oceanic crust and carbonate sediment in the Equatorial Pacific: Lithium abundance and isotopic evidence

Creator:: You, Chen-Feng, Chan, L.-H., Gieskes, J. M., and Klinkhammer, Gary P.
Abstract:: Large-scale lateral advection of seawater within the oceanic crust is thought to be the cause of low heat flow in the Equatorial Pacific. Until now supportive evidence is limited to reversals of B and δ¹¹B, Ca, Mg, SO₄⁻², Sr and ⁸⁷Sr/⁸⁶Sr in sediment pore waters. Here we report new evidence...

Evolution of 1996-1999 La Niña and El Niño conditions off the western coast of South America: A remote sensing perspective

Creator:: Carr, Mary-Elena, Strub, P. Ted, Thomas, Andrew C., and Blanco, Jose Luis
Abstract:: We present the evolution of oceanographic conditions off the western coast of South America between 1996 and 1999, including the cold periods of 1996 and 1998–1999 and the 1997–1998 El Niño, using satellite observations of sea level, winds, sea surface temperature (SST), and chlorophyll concentration. Following a period of cold...

Subducted seamounts and recent earthquakes beneath the central Cascadia forearc

Creator:: Tréhu, Anne M., Blakely, Richard J., and Williams, Mark C.
Abstract:: Bathymetry and magnetic anomalies indicate that a seamount on the Juan de Fuca plate has been subducted beneath the central Cascadia accretionary complex and is now located similar to 45 km landward of the deformation front. Passage of this seamount through the accretionary complex has resulted in a pattern of...
