Identification of Drivers of Change of the Gulf of Nicoya Ecosystem (Costa Rica) [PDF]
Frontiers in Marine Science, 2020 The Gulf of Nicoya is a large tropical estuary located on the Pacific coast of Costa Rica and accounts for the country’s main fish production. It is increasingly impacted not only by its fisheries, but also by urbanization, tourism developments, the ...

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 ...

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 ...

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 ...

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
