Abstract

Biomass is a valuable indicator of biological production in any ecosystem and represents a proxy of secondary production in the case of zooplankton. This short communication aims to report zooplankton biomass values in the waters of the Campeche Canyon, southern Gulf of Mexico, during the "Nortes" storm season of 2011 and to explore their relationship with the hydrography and the circulation pattern. The results showed the presence of cyclonic and anticyclonic eddies associated with high and low water density at the base of the pycnocline. The highest values of zooplankton biomass (>40 g 100 m-3) were observed in regions that presented higher water density values (~26.1 kg m-3). In comparison, the lowest zooplankton biomass values (<5 g 100 m-3) were associated with low water densities (<25.6 kg m-3). The results presented here contribute to elucidating the role that physical forcing plays on the zooplankton biomass of the region, particularly during a season in which the passage of extreme storms is widespread.

2011年“Nortes”风暴季节坎佩切峡谷（墨西哥湾南部）浮游动物生物量评估

生物量是任何生态系统中生物生产的一个有价值的指标，也是浮游动物二次生产的代表。这份简短的通讯旨在报告2011年“Nortes”风暴季节墨西哥湾南部坎佩切峡谷水域的浮游动物生物量值，并探讨它们与水文和环流模式的关系。结果表明，在比重跃层底部存在与高和低水密度相关的气旋和反气旋涡旋。浮游动物生物量的最高值（>40 g 100 m-3）出现在水密度值较高（~26.1 kg m-3）的地区。相比之下，最低的浮游动物生物量值（<5 g 100 m-3）与低水密度（<25.6 kg m-3）有关。本文给出的结果有助于阐明物理作用力对该地区浮游动物生物量的影响，特别是在极端风暴普遍通过的季节。

期刊介绍： Latin American Journal of Aquatic Research- LAJAR is the continuation of the journal Investigaciones Marinas (1970-2007) and is published since 2008 by the Escuela de Ciencias del Mar, Facultad de Ciencias del Mar y Geografía of the Pontificia Universidad Católica de Valparaíso. LAJAR is an “Open Access” journal that publishes in English language, original research articles, reviews and short communications on aquatic science, which contain the results of research conducted in aquaculture or in oceanic and coastal marine waters of Latin America. The following topics are considered: Physical Oceanography, Chemical Oceanography, Marine Biogeochemistry, Marine Pollution and Toxicology, Marine Geology and Geophysics, Biological Oceanography, Fisheries and Aquaculture.
