Oceanographic data acquired during the ABRIC-4 Cruise (29GD20230310) on board the Research Vessel García del Cid in 2023., Assessment of Bottom‐trawling Resuspension Impacts in deep benthic Communities (ABRIC)

Oceanographic data acquired during the ARCO Cruise (29GD20230626) on board the Research Vessel García del Cid in 2023., Assessment of fishing grounds Restoration after a Change of bottom trawling Otter boards (ARCO). The main objective of the ARCO project is to study the current sedimentary processes related with trawling activity in the Palamós submarine canyon after the change of trawl doors by the Palamós harbor fleet. The impacts of this type of fishing in deep-sea environments are considered very high due to their intensity and recurrence, and to the fact that sediment dynamics are less energetic and the benthonic ecosystems are more vulnerable and have less resilience than in neritic or shelf environments

Dades experimentals a partir de les quals s'han calculat activitats enzimàtiques i expressions d'enzims (i altres proteïnes) relacionats amb el cicle de la urea en diferents localitzacions (masses) de teixit adipós blanc de rates (mascles i femelles). Els arxius contenen les dades experimentals directes i els paràmetres de control i de referència, derivats dels animals, que han estat processats per a la publicació. També inclouen algunes fases del processament de les dades per assolir els resultats finals, de forma que el conjunt es pugui comprendre globalment.

Dades experimentals de la recerca on s'ha provat de veure si l'administració d'una dieta hiperlipídics (dieta de cafeteria) a rates mascles durant 30 dies, modifica la distribució del flux de sang entre els diferents teixits. Això s'ha fet mitjançant l'administració de microesferes fluorescents. S'ha pogut comprovar que hi ha un augment de flux cap el teixit adipós marró, pulmons i cor i una disminució cap a la pell. Això confirma l'augmenten en els teixits que controlen l'energia dissipada.

El material que es diposita correspon a les dades experimentals, i part del procés de tabulació d'aquestes, d'un estudi de distribució d'àcids grassos en el lípids d'un nou compartiment lipídic dels glòbuls vermells de rata.

Data of hydrographic properties (pressure, temperature, salinity and turbidity) collected by an autonomous hydrographic profiler deployed in the axis of the Palamós Canyon (NW Mediterranean), and near-bottom time series of turbidity and currents. Additionally, data (temperature, salinity and turbidity) collected during an hydrographic CTD transect across the Palamós Canyon's head is also provided, Increases of water turbidity and suspended sediment transport in submarine canyons have been associated with high-energy events such as storms, river floods and dense shelf water cascading (DSWC), and occasionally with bottom trawling along canyon flanks and rims. To assess the variations on the water column turbidity and sediment transport in the Palamós Canyon linked to both natural and trawling-induced processes, an autonomous hydrographic profiler, as well as a near-bottom current meter and a turbidimeter were deployed in the canyon axis (929 m depth) from February to June 2017, covering a trawling closure (February) and trawling activities (March-June). Periods of enhanced water turbidity during the trawling closure were mostly associated with storms and DSWC events, transporting turbid dense waters into the canyon. In absence of such events, the water column displayed low suspended sediment concentrations (~ 0.3 mg L− 1) until the trawling season began, when particulate matter detachments, ranging between > 1 mg L− 1 and 3.8 mg L− 1, were observed at the water depths where the trawling grounds are found. During the trawling closure, high near-bottom suspended sediment fluxes (35–44 g m− 2 s− 1) were sporadically registered at ~  920 m depth associated with a major storm and DSWC event. Smaller but more frequent increases of near-bottom suspended sediment fluxes (0.1–1.4 g m− 2 s− 1) were recorded during trawling activities. Despite these smaller trawling-induced suspended sediment fluxes, 30 days of continuous bottom trawling activity transported a total amount of 40 kg m− 2, of similar magnitude to that generated by a major DSWC event (50 kg m− 2). Since bottom trawling in Palamós Canyon is practiced on a daily basis throughout the year, a much larger contribution of anthropogenically derived water turbidity and suspended sediment transport can be expected, Ministerio de Economía y Competitividad (España) MINECO/CTM2015-65142-R, MINECO/BES-2016-076983; Ministerio de Ciencia, Innovación y Universidades (España): AGAUR/2017/SGR-863, AGAUR/2017/SGR-1241, No

PASTA Cruise (29GD20021024) carried out on the Research Vessel García del Cid in 2002, One of the priority objectives of the campaign is to anchor instruments to measure the transport of sediment in energy conditions, the dates of the start of the campaign have to coincide with the time when river discharges and storms begin to occur in the Adriatic. This study covers the mouth of the Po River up to the promontory of Gargano (more than 200 miles from the coast), along which several oceanographic instruments will be anchored next to protective buoys and sediment coorers will be obtained in the prodelta of the Po river and in front of the most important Apennine rivers.Probes, thermosalynograph, Doppler, meteorological station, Boxcorrer, mini-CTD with particle chamber, an x-ray apparatus for radiography of sediments, current meters, temperature sesores, oceanographic tripods and protection buoys will be used

ABIDES-1 Cruise (29GD20170205) carried out on the Research Vessel García del Cid in 2017, To study the transport processes from the submarine canyon flanks of the Catalan margin to deeper areas caused by the bottom trawling activities and evaluate the impact on the sedimentary substrate.To address several of the specific objectives proposed in this project objectives it will be necessary to carry out three separate oceanographic campaigns six months each other to record time series of oceanographic parameters through the anchorage of several anchors equipped with current meters, turbidimeters and sediment traps located inside submarine canyons . In the first of these campaigns, we will proceed to anchoring the anchors, in the second to the maintenance and in the third to the final recovery of the instruments, to cover an annual cycle of record the sediment transport processes and identify the contribution of the resuspension by trawling to sedimentary flows . In each one of these campaigns will be transects of CTD stations to study the seasonal variability of hydrography and formation of nephelloid layers in the column of water and surface sediment cores will be obtained . Sampling will be done both in open slope environments and in the interior of canyons submarines. The oceanographic vessel chosen for these three campaigns is the B / O García del Cid, which has the right characteristics to carry out the tasks planned and the crew is experienced with anchoring maneuvers and recovery of oceanographic anchors
