Abstract The present state of deoxygenation in the northern limits shallow oxygen minimum zone off Mexico is examined order to detect its effects on larval fish habitats and consider sensitivity larvae decreased dissolved oxygen. A series cruises between 2000 2017 indicated a significant vertical expansion low waters. upper limit suboxic conditions (<4.4 μmol/kg) has risen ~100 m at 19.5°N Cabo Corrientes ~50 25°N mouth Gulf California. habitat distribution was related geographic...
Abstract Four underwater glider missions were carried out to sample the physical and bio‐optical properties inside a Loop Current Eddy (LCE) in Gulf of Mexico, investigate whether winter deepening mixed‐layer erosion nitracline stimulates phytoplankton growth. Recent coupled physical‐biogeochemical numerical models support this mechanism, but observations using profiling floats suggest that there is no seasonal cycle on integrated biomass. Here, data collected by gliders during full LCE...
Golfo Dulce es un estuario en forma de fiordo, localizado el Pacífico Sur Costa Rica. Este ecosistema marino-costero contiene una importante biodiversidad marina que incluye cetáceos. estudio describe la estructura comunidad cetáceos Dulce, sustentado diversidad hábitats. Datos sobre avistamientos colectados muestreos periódicos sistemáticos, han resultado 943 registros (2005-2014≈3 490h≈64 533km) siete especies familia Delphinidae, Balaenopteridae y especie Kogiidae. Se observa gradiente...
This study aims to describe the response of two persistent chlorophyll-a maxima physical processes that affect po- sition thermocline/nitracline in Eastern Tropical North Pacific (ETNP). We focused on Long Rossby Waves (LRWs) due their relevance ETNP circulation and potential role introducing nutrients into euphotic zone. found shallower maximum oxygenated waters became more intense when denser (containing nu- trients) moved toward surface. suggests changes isopycnals nitracline...
We present new results of the coccolith fluxes in Perdido and Coatzacoalcos regions Gulf Mexico explore environmental variables that may control them. Two sediment trap moorings located at a water depth 1100 m collected settling particles from June 2016 to July 2017. Both showed similar seasonal distributions total fluxes, with highest recorded during winter, decreasing through spring, moderate summer autumn. The shows slightly higher annual average 3.09 x 109 ± 0.89 coccoliths per m-2d-1,...
Four underwater glider missions were carried out to sample the physical and bio-optical properties inside a Loop Current Eddy (LCE) in Gulf of Mexico (GoM), investigate whether winter deepening mixed-layer erosion nitracline stimulates phytoplankton growth. Recent coupled physical-biogeochemical numerical models support this mechanism, but observations using Lagrangian floats suggest that there is no seasonal cycle on integrated biomass. Here, data collected by gliders during full LCE...
Se describe la distribución geográfica y batimétrica de Squalus cubensis capturados a bordo del B/O Miguel Oliver en costa Caribe Centroamérica, durante una campaña prospección pesquera realizada 3 enero hasta el febrero 2011. analizaron 96 lances, se capturaron 140 individuos (65 machos 75 hembras) 24 100 cm longitud total, entre 70 040 grs peso total. En cuanto talla, encontró marcada diferencia que indica dimorfismo sexual. La relación talla-peso para ambos sexos no presentó diferencias...
This study aims to describe the response of two persistent chlorophyll-a maxima physical processes affecting thermocline and nitracline position in Eastern Tropical North Pacific (ETNP). We focused on Long Rossby Waves given their relevance ETNP circulation its potential as a mechanism introducing nutrients into euphotic zone. found shallower maximum oxygenated waters became more intense when denser (more nutrients) moved toward surface. It suggests that isopycnals displacements modify...
