North-east Atlantic mackerel spawning distribution has shifted northward in the last three decades probably response to global sea warming. Yet, uncertainties subsist regarding on shift rate, causalities, and how this species will respond future conditions. Using egg surveys, we explored influence of temperature change mackerel's (western southern components stock) between 1992 2013, projected it may under climate scenarios. We developed generalized additive models: (i) a spatiotemporal...
Abstract The Bay of Biscay anchovy has experienced, since 2001, a succession low recruitments, resulting in the collapse stock 2005; this led to successive closures fishery. This study investigates possible impact different controlling factors [North Atlantic Oscillation (NAO), East (EA) pattern, turbulence, upwelling, and river flow] upon recruitment fishery catches. Fifty‐five percent variability can be explained by upwelling over spawning area; is related, turn, EA pattern. conceptual...
[1] HF radar surface current data together with from two operational offshore oceanographic buoys located over the slope are used to map variability associated near-inertial waves, during a target year (2009), in SE Bay of Biscay. The results obtained show complex 4D distribution inertial oscillations this area. We find very pronounced horizontal structure across area ranges factor 5 kinetic energy. This pattern presents also strong seasonal variability, peak KE closer shelf-break summer,...
Abstract Marine species have exhibited trends in their geographic distribution and phenology recent decades, these changes are triggered by climate variability or anthropogenic pressures. Northeast Atlantic albacore has recently been identified to show of this nature, although the underlying causes still uncertain. The aim work was analyse shifts phenological during trophic migration that juveniles undertake from late spring autumn identify potential such variability. Specifically, time...
This study describes, for the first time, annual variability of phytoplankton community in different layers water column open waters off Basque coast (southeastern Bay Biscay). Phytoplankton composition, abundance and biomass, together with size-fractionated chlorophyll a, nutrients, optical hydrographic conditions were measured an experimental bivalve culture area from May 2014 to June 2015. Water showed typical dynamics previously described temperate areas, characterised by winter...
Abstract. The combination of remotely sensed gappy Sea surface temperature (SST) images with the missing data filling DINEOF (data interpolating empirical orthogonal functions) technique, followed by a principal component analysis reconstructed data, has been used to identify time evolution and daily scale variability wintertime signal Iberian Poleward Current (IPC), or Navidad, during 1981–2010 period. An exhaustive comparison existing bibliography, vertical salinity profiles related its...
Abstract The short‐term (less than 20 days) response of surface circulation to wind has been determined in waters the southeastern Bay Biscay, using impulse (time domain) and transfer (frequency functions relating high‐frequency radar currents reanalysis winds. is amplified at near‐inertial frequency low‐frequency it varies spatially. analysis indicates that ocean slightly anisotropic, likely due pressure gradients friction induced by bottom coastline boundaries this region. Thus, function...
Abstract Decreased body size is often cited as a major response to ocean warming. Available evidence, however, questions the actual emergence of shrinking trends and prevalence temperature‐driven changes in over alternative drivers. In marine fish, food availability or fluctuations abundance, including those due size‐selective fishing, provide compelling mechanisms explain size. Here, based on three decades scientific survey data (1990–2021), we report decline average size—length weight—of...
During 2000 and 2001 at the beginning of 2002, current meters were deployed 25, 50 110 m water depths along two transects: one offshore San Sebastian other Hondarribia.At same time, hydrographical cruises collection sediment samples undertaken over coastal section.The aim study was to improve knowledge seasonal changes in circulation.The main results obtained are three-dimensional measurements flow, a description seabed sedimentology between 90 depth, an improved effect circulation patterns...
