On October 10 2011 an underwater eruption gave rise to a novel shallow submarine volcano south of the island El Hierro, Canary Islands, Spain. During large quantities mantle-derived gases, solutes and heat were released into surrounding waters. In order monitor impact on marine ecosystem, periodic multidisciplinary cruises carried out. Here, we present initial report extreme physical-chemical perturbations caused by this event, comprising thermal changes, water acidification, deoxygenation...
The short-term variability of plankton communities in the oceanic realm is still poorly known due to paucity high-resolution time-series open ocean. Among these few studies, there compelling evidence a lunar cycle epipelagic zooplankton biomass subtropical waters during late winter bloom. However, information about lower trophic levels and physiological changes related this cycle. Here, we studied pico-, nano-, micro-, mesoplankton relation waters. Weekly sampling was carried out at four...
Ship echosounders are essential tools for observing the distribution of organisms within water column. They enable study deep pelagic fauna, likely most extensive and abundant animal community in global ocean, yet also one least studied. Until now, observations have been constrained by costly clearly insufficient fishing efforts vast challenging ecosystems planet. This situation can now be alleviated through use sonar observations. Every day, national research fleets worldwide cover...
Micronekton comprises a diverse assemblage of actively swimming aquatic animals in oceanic ecosystems, including mesopelagic fishes from 2 to 20 cm. They live the zone (200-1000 meters), characterized by high environmental gradients and distinct temporal dynamics across depth layers. Depending on their vertical habitat, have developed various adaptions contribute essential ecosystem processes, nutrient cycling carbon transport. However, link between functional diversity, habitat use survival...
Ocean dynamics initiate the structure of nutrient income driving primary producers, and these, in turn, shape distribution subsequent trophic levels until whole pelagic community reflects physicochemical ocean. Despite importance bottom-up structuring ecosystems, fine-scale studies biophysical interactions along depth are scarce challenging. To improve our understanding such relationships, we analyzed vertical key oceanographic variables with acoustic biomass from multi-frequency data (38,...
Abstract Oceanic eddies are recognized as pivotal components in marine ecosystems, believed to concentrate a wide range of life spanning from phytoplankton top predators. Previous studies have posited that predators drawn these due an aggregation their forage fauna. In this study, we examine the response fauna, detected by shipboard acoustics, across broad sample thousand world’s oceans. While our findings show impact on surface temperatures and most cases, they reveal only minority (13%)...
The submarine volcano eruption off El Hierro Island (Canary Islands) on 10 October 2011 promoted dramatic perturbation of the water column leading to changes in distribution pelagic fauna. To study response scattering biota, we combined acoustic data with hydrographic profiles and concurrent sea surface turbidity indexes from satellite imagery. We also monitored plankton nekton communities through eruptive post-eruptive phases. Decrease oxygen, acidification, rising temperature deposition...
Abstract Aim Water column acoustic backscatter is regularly registered during oceanographic surveys, providing valuable information on the composition and distribution of pelagic life in ocean. We propose an objective approach based functional data analysis to classify these seascapes into biogeographical regions. Location Tropical South Atlantic Ocean off northeastern Brazil. Taxon Sound‐scattering fauna detected with echosounders, principally small fish, crustaceans, squid diverse...
