title: Environmental, oceanographic and fisheries strategy time series (2000-2019) for demersal species in the Brazilian Meridional Margin

description: The 'Mean Temperature of Catch (MTC)' was estimated for each year of the time series, as proposed by Cheung et al. (2013). This variable is expressed in degrees Celsius. 'Sea Bottom Temperature (SBT)' was derived from estimates provided by the high-resolution ocean general circulation INALT20 model (Schwarzkopf et al., 2019) for the study period (2000-2019) and was calculated by averaging the temperatures over 0.25° x 0.25° grid cells of the BMM and a water column up to 50 m above the seafloor. This variable is expressed is degrees Celsius. 'Annual volume transports of the Brazil-Malvinas confluence (BCt)' was extracted and compiled from Artana et al. (2019). This index was estimated for the period between 2000 and 2017. More detailed information about this index can be accessed in Artana et al. (2019). This variable expressed in Sverdrups (Sv). 'Simpson diversity index (Dm)' express the diversity of demersal fishing métiers (i.e. combination of target species, gear, and time of the year) operating each year of the time series, as determined by a process of classification of individual fishing trips. Catches of each métier operating during each year of time series summed and used to calculate Dm using the Simpson species diversity index formulation.

title: Catch composition time series (2000-2019) for demersal species in the Brazilian Meridional Margin

description: This dataset contains information on catches reported in the harbours of Santa Catarina state, southern Brazil, between the years 2000 and 2019. Historically, these harbours have concentrated a significant part of the demersal fishing fleet that operates widely on the Brazilian Meridional Margin (BMM), from 21°S to the southern border of Brazilian EEZ (34°S) and from the coastal areas down to 500 m depths. Landed catches were monitored by a research team based on the University of 'Vale do Itajaí' (UNIVALI) along a sequence of scientific projects and contracts developed to meet governmental demands for oceanic and deep fisheries development and management, and in support of the licensing processes of the offshore oil and gas exploration activities.This catch composition time series shows an annual compilation of total catches discriminated by species caught by trawlers (single trawlers, pair or twin trawlers and double trawlers) and gill net industrial fisheries. These species represent altogether over 81% of total reported catch in the period. The remainder amount of landings was reported as groups of species (e.g. sharks) or categories indiscriminated by species and were excluded from the database.

title: Water parameters from a long-term (12-months) multiple driver aquarium experiment with the cold-water coral Desmophyllum pertusum

description: We conducted a long-term (12 months) multiple driver aquarium experiment under future environmental conditions at St Abbs Marine Station (UK) with the cold-water coral Lophelia pertusa (syn. Desmophyllum pertusum) sampled from Tisler Reef (Skagerrak). The experiment consisted of four different treatments to investigate the combined effect of ocean acidification, warming, deoxygenation and food limitation on their physiology: 1) control (9 °C, pH 8.1, 100 % oxygen, 100 % food availability), 2) multiple stressor with high feeding (HF; 12 °C, pH 7.7, 90 % oxygen, 100 % food availability), 3) multiple stressor with low feeding (LF; 12 °C, pH 7.7, 90 % oxygen, 50 % food availability) and 4) reduced oxygen (9 °C, pH 8.1, 90 % oxygen, 100 % food availability). Every treatment consisted of three replicate tanks with four live corals (12 in total). Water parameters (temperature, salinity, pH and oxygen concentration) were measured five times per week in every coral tank.

title: Dendrometer and meteorological data from the TreeNet network, year 2010

description: The timing of diel stem growth of mature forest trees is still largely unknown, as empirical data with high temporal resolution have not been available so far. Consequently, the effects of day-night conditions on tree growth remained uncertain. Here we present the first comprehensive field study of hourly-resolved radial stem growth of seven temperate tree species, based on 57 million underlying data points over a period of up to 8 years. We show that trees grow mainly at night, with a peak after midnight, when the vapour pressure deficit (VPD) is among the lowest. A high VPD strictly limits radial stem growth and allows little growth during daylight hours, except in the early morning. Surprisingly, trees also grow in moderately dry soil when the VPD is low. Species-specific differences in diel growth dynamics show that species able to grow earlier during the night are associated with the highest number of hours with growth per year and the largest annual growth increment. We conclude that species with the ability to overcome daily water deficits faster have greater growth potential. Furthermore, we conclude that growth is more sensitive than carbon uptake to dry air, as growth stops before stomata are known to close.

The physiological parameters (survival, growth and respiration rate) were determined after 1.5, 3, 4.5, 6, 7.5, 9, 10.5 and 12 months of the experiment. Growth rates were measured using the buoyant weighing technique (Jokiel et al. 1978) with a high precision electronic balance (Pioneer Plus PA224C, OHAUS; precision: 0.1 mg) every 1.5 months. The skeletal dry mass of each coral was calculated from its wet mass and by taking into account the densities of seawater (1.023 ± 0.008 g cm-3) and L. pertusa skeletons (2.747 g cm-3; Naumann et al., 2014). Respiration rates were measured in closed-cell incubations vials in a water bath at the start of the experiment and every 1.5 months. In addition, the energetic reserves (protein, carbohydrate and lipid concentration) of six coral samples per treatment were analysed after 3, 6, 9 and 12 months. The protein, carbohydrate and lipid concentrations were then converted to kilojoules (kJ; protein: 23.9 kJ g-1, carbohydrate: 17.5 kJ g-1, lipid: 39.5 kJ g-1; Gnaiger & Bitterlich, 1984).

title: High resolution carbon dioxide, methane, and nitrous oxide concentrations and emissions measurements in the Great Barrier Reef lagoon, Australia

description: Greenhouse gas emission studies from Coral Reef settings remain sparce compared to open ocean, rivers, and estuaries. Here we sampled the greenhouse gases of carbon dioxide (CO2) with isotopic fractions (δ13C-CO2), methane (CH4) with isotopic fractions (δ13C-CH4), and nitrous oxide (N2O) in high resolution (905 individual georeferenced 5 minute averaged samples) from ship based cruises throughout the southern half of the Great Barrier Reef Australia. Time and location matched high-resolution physio-chemical data (salinity, temperature, dissolved oxygen, turbidity and chlorophyll a) were also measured to determine driving factors of greenhouse gases in the lagoon. Overall, the lagoon was oversaturated in CO2 which is consistent with previous coral reef area studies. CH4 was also oversaturated despite highly oxygenated waters that are normally unconducive for CH4 production. N2O was undersaturated and up-taking N2O from the atmosphere which contrasts with the few coral reef and continental shelf area studies.Dissolved greenhouse gases were measured with a Picarro G2201-i Cavity Ring Down Spectrometer for CO2 (200 ppb ±0.05%) and CH4 (5 ppb ± 0.05%) with respective δ12C and δ13C stable isotope fractions and a Picarro G2308 Cavity Ring Down Spectrometer for N2O concentrations (&lt;3.5 ppb ± 0.008%). Both Cavity Ring Down Spectrometer instruments were connected in a closed loop with twin showerhead exchangers and a gas drying agent (Drierite). The showerhead exchangers received seawater from the vessel cold water intake. Both instruments averaged 300 measurements over a five-minute cycle for each greenhouse gas sample. Salinity, temperature, and turbidity were also recorded at the inlet of the seawater system with a Seabird SBE 21 (salinity ± 0.005 psu, temperature ± 0.002 °C, turbidity ± 0.04% NTU). Dissolved oxygen, pH, and Chlorophyll were recorded using respective Hydrolab MS5 multi-parameter sonde (dissolved oxygen 0.1 ± 0.02 mg L-1), SAMI-pH (&lt;0.001 ± 0.003 pH units) and ECO 3-Triplet fluorometer (Chl-a 0.016 ± 0.025 μg L-1) instruments fitted with inline flow cells.

title: Continuous meteorological observations at the Naples's harbor weather station (Naples, Italy) during the period Jan. 2022 - Dec. 2022

description: Weather data monitoring is ongoing since 2013 in a network of four sites located in the metropolitan area of Naples (Italy) in the framework of the MONICA (Innovative Monitoring of Coastal and Marine Environment) Project. The aim of this activity is to acquire time series to analyze the influence of meteorological factors on geomorphological coastal processes, such as cliff retreat, landslides and beach erosion. To this three sites has been added a new monitoring site in the Port of Naples, to delimit to the east the overall monitoring area. The uploaded dataset includes various meteorological parameters (temperature, relative humidity, wind, barometric pressure and rain) acquired at the Naples's harbor automatic weather station (model: DAVIS Vantage Pro2 wireless) during the period Jan. 2022 - Dec. 2022. Automatic data transfer from the weather station to the ISMAR-CNR processing center of Naples is performed by an internet LAN connection.

title: Temperature, salinity, CO2, dissolved inorganic nutrients, plankton stoichiometry of indoor mesocosm experiment 2014

description: Previous studies with Baltic Sea phytoplankton combining elevated seawater temperature with CO2 revealed the importance of size trait-based analyses, in particular dividing the plankton in-to edible (&gt; 5 and &lt; 100 µm) and inedible (&lt; 5 and &gt; 100 µm) size classes for mesozoopankton grazers. While the edible phytoplankton responded predominantly negative to warming and the inedible group stayed unaffected or increased, independent from edibility most phyto-plankton groups gained from CO2. Because the ratio between edible and inedible taxa changes profoundly over seasons, we investigated, if community responses can be predicted according to the prevailing composition of edible and inedible groups. We experimentally explored the combined effects of elevated temperatures and CO2 concentrations on a late-summer Baltic Sea community. Total phytoplankton significantly increased in response to elevated CO2 in particu-lar in combination with temperature, driven by a significant gain of the inedible &lt; 5 µm fraction and large filamentous cyanobacteria. Large flagellates disappeared. The edible group was low as usual in summer and decreased with both factors due to enhanced copepod grazing and overall decline of small flagellates. Our results emphasize that the responses of summer communities are complex, but can be predicted by the composition and dominance of size classes and groups.

title: Multibeam bathymetry raw data (Kongsberg EM710 entire dataset) of RV METEOR during cruise M191

description: Raw multibeam bathymetry data were collected aboard RV METEOR during cruise M191 using a Kongsberg EM 710 multibeam echosounder. The expedition took place during 16.07.2923 – 05.08.2023 from Algeciras (Spain) to Piraeus (Greece) in the Mediterranean. The main objective of M191 was to extensively map the seafloor (with multibeam echo sounder, sediment echo sounder, and towed magnetometer) and sample (by chain bag dredging) unexplored volcanic structures along the Sicilian Channel Rift Zone (Pantelleria-, Malta- and Linosa-Graben) and the Capo-Granitola-Sciacca Fault Zone (CGSFZ).Data were recorded in the Italian and Greek EEZ. Sound velocity profiles (SVP) were applied on the data for calibration. Please see environmental data and the cruise report for details. The data are unprocessed and can therefore contain incorrect depth measurements (artifacts) if not further processed. Note that refraction errors may occur when no proper SVP is applied. Acquisition and provision of the data are part of the DAM Underway Project and published according to the FAIR principles.
