Geophysical Research Letters, 2002 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 ...

Microbial source tracking in shellfish harvesting waters in the Gulf of Nicoya, Costa Rica [PDF]
Water Research, 2017 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 ...

The Gulf of Nicoya (Costa Rica) Fisheries System: Two Decades of Change [PDF]
Marine and Coastal Fisheries, 2019 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 ...

Fisheries assessment of Callinectes arcuatus (Brachyura, Portunidae) in the Gulf of Nicoya, Costa Rica [PDF]
Fisheries Research, 2006 The Callinectes arcuatus population of the Gulf of Nicoya and its current level of exploitation were investigated based on size frequency analysis of trap and trawl catches. Von Bertalanffy growth parameters (K = 0.89; CW∞ = 142 mm for males) are in the range reported for other species of this family and suggest that the male size at first maturity (CW

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]
, 2009 The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

Hydroacoustic estimation of fish biomass in the Gulf of Nicoya, Costa Rica
Revista de Biología Tropical, 1969 Se utílizó un diseño muestral estratificado para llevar a cabo una evaluación hidroacústica de la sección interior del Golfo de Nicoya. La topografía submarina fue modelada introduciendo el concepto topográfico de la cuenca, como una forma de proyectar los estimados del muestreo a todo el Golfo interno.
