Tomographic images constrain the existence of a subducted seamount beneath the Gulf of Nicoya, Costa Rica. The subducted seamount is found at a depth of 30 km within the rupture area of the March 25, 1990, Mw = 7.0 Gulf of Nicoya earthquake. The Gulf of Nicoya earthquake was a typical thrust‐type subduction earthquake and occurred on a shallow dipping ...

Wind driven upwelling in the Gulf of Nicoya, Costa Rica
International Journal of Remote Sensing, 2003Using satellite sensor data and information from local meteorological stations, a transient upwelling event in the Gulf of Nicoya, Costa Rica, has been observed during the period 6-8 March 1997 in coincidence with strong upwelling in the Gulf of Papagayo.

The Gulf of Nicoya (Costa Rica) Fisheries System: Two Decades of Change [PDF]
Abstract In the early 1990s, ecological and fishery data from the Gulf of Nicoya (Pacific Ocean) were holistically analyzed, and a trophic model was constructed using the Ecopath modeling approach. The results indicated that this tropical estuary, which is a Costa Rican fishery hot spot, was already overexploited by shrimp trawlers and ...

Microbial source tracking in shellfish harvesting waters in the Gulf of Nicoya, Costa Rica [PDF]
Current microbial water quality monitoring is generally limited to culture-based measurements of fecal indicator bacteria (FIB). Given the many possible sources of fecal pollution within a watershed and extra-intestinal FIB reservoirs, it is important to determine source(s) of fecal pollution as a means to improve water quality and protect public ...

Polychaetous Annelids from the Gulf of Nicoya, Costa Rica†
International Review of Hydrobiology, 1988AbstractPolychaetous annelids from a soft bottom community (1–46 m) were sampled from the Gulf of Nicoya, Costa Rica. A total of 125 species was identified, 120 from a faunistic study throughout the gulf and 78 species from a time study at four stations. The number of species from the Gulf was not as high as in some temperate areas.

Benthic invertebrates of a tropical estuary: Gulf of Nicoya, Costa Rica
Journal of Natural History, 1984Summary Crustaceans showed considerable differential distribution in response to a variety of features. Portunid crabs may be responding to salinity gradients, peak abundance of shrimp may be associated with detritus from rivers flowing into the Gulf and mantis shrimp may be influenced by sediment type and biotic interactions.

Ecological assessment of finfish as indicators of habitats in the Gulf of Nicoya, Costa Rica
Hydrobiologia, 1984Trawl samples of demersal fish populations within the Gulf of Nicoya, Costa Rica were conducted during February and July, 1979 and April, 1980 in an attempt to define basic abundance, diversity and distributional patterns. Seventeen day and three night samples produced 6 441 fishes of 107 species during the February cruise.

The estuarine character of the Gulf of Nicoya, an embayment on the Pacific coast of Central America
Hydrobiologia, 1983Hydrography and exchange processes in a tropical estuary, the Gulf of Nicoya, Costa Rica, are described from data collected in 1979 and 1980. The measurements and analyses were made in both the dry season and wet season and include temperature, salinity, and density at twenty locations in the gulf and currents (over a semi-diurnal tidal cycle) at five ...

DISTRIBUTION, ABUNDANCE, AND SEXUAL COMPOSITION OF STOMATOPODS IN THE GULF OF NICOYA, COSTA RICA
Journal of Crustacean Biology, 1991ABSTRACT Stomatopod Crustacea were collected by trawling in the Gulf of Nicoya on the Pacific Coast of Costa Rica. Abundances, size-frequency distributions, and sexual composition were measured at 12 stations. Eight stations in the upper, more estuarine regions of the Gulf were sampled monthly, while the 4 stations in the lower Gulf were sampled ...
