Physical data associated with the AMAZOMIX cruise. The Amazon shelf encompasses a variety of physical processes, such as fluvial inputs, coastal currents, mesoscale, filaments, tides, internal waves and upwelling, influencing nutrient concentrations, chlorophyll and suspended matter. They also affect energy, salt and heat balances; parameters that condition physical/biogeochemical interactions and ecosystem functioning, from bacteria to plankton to fish resources. In particular, internal tidal waves are very energetic in this region. They impact biogeochemical cycles via the vertical mixture induced by their dissipation or vertical movements induced by their propagation. They thus allow a significant input of nutriments into the euphotic layer enhancing primary production, as observed on the surface from watercolour data. Internal tidal waves could thus influence the biological pump and the carbon cycle. In addition, overall marine biodiversity of the region, from bacteria to fish is not well described. The connectivity of species in the tropical Atlantic is also still an open question. The Caribbean region is by far more bio-diverse than the Brazilian one. One of the hypotheses is that the Amazon plume, which can extend up to 3,000 km off the mouth, would constitute a barrier for some organisms. The Amazon Shelf is thus an ideal experimental laboratory to study the impact of physical processes on the structure and function of neritic and oceanic marine ecosystems. In this context, the objective of the multidisciplinary AMAZOMIX survey was to study the impact of the Amazon River plume, internal tides and associated turbulent mixing, on marine ecosystem in contrasting regions off the Amazon shelf. For that purpose, the multidisciplinary AMAZOMIX project brings together physicists, biogeochemists, bioopticians and biologists. The sampling strategy consists in the simultaneous acquisition of a comprehensive set of environmental and biological compartments, including micro-organisms (bacteria, phyto and zooplankton) and higher trophic levels (micronekton, demersal and pelagic fish). AMAZOMIX is the first campaign to develop this multi-disciplinary approach off the Amazon shelf. In situ results will be analysed in interaction with digital tools and data, modelling (1/36°, with and without tides, 1/12° coupled) and satellite data analyses.

This dataset contains current data acquired between September 2016 and July 2017 using 2 TCM3 Ocean Bottom Tilt Current Meters installed next to the Tour Eiffel and Montségur hydrothermal vent sites. The TCM-3 Ocean Bottom Tilt Current Meter from Lowell Instruments LLC (North Falmouth, MA, USA) measures current using the drag-tilt principle. The logger is buoyant and is anchored to the bottom via a short flexible tether. Drag from moving water tilts the logger in the direction of flow. The logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). The array comprised 3 currentmeters, deployed near the Tour Eiffel, Montségur and White Castle hydrothermal vent sites (the instrument at White Castle did not recover data). The array is not connected to an energy node. The currentmeter's internal clocks are set to UTC time before deployment. Clock drift after recovery is not implemented in data but added as metadata in the file "Sites and Sensor metadata".

This campaign was carried out on May 15, 2021 on the route between Puerto Juárez and the Arrowsmith Bank course or “Bajo del Este”, as the fishermen call it. The bank is located 40 km east of Punta Cancun at coordinates 21°05'00''N-86°28'00''W. The ship's captain Guillermo Antonio Carrillo Corzo alias the "Teacher", a pilot (Cap. Watermelon) and a sailor (El Chalán). The goal was carry out temperature and salinity measurements in the water column at each of the CTD stations. Direction: 10 stations with a separation of 4 km between each one were planned. Stations 1 to 6 were covered without difficulty; however, at station 7 the waves and the current increased their intensity considerably, so no progress was made to the following stations. the diagram salinity temperature profiles of each station (aligned West to East) The salinity is between 35 and 36 UPS and in turn from 28 °C to 25.5 °C. The depth ranges at the stations were from 1 to 57 m deep.

Socheongcho Ocean Research Station (Socheongcho ORS) opened in October 2014, and was built to help advance the understanding of the dynamics of the Yellow Sea, including its influence on Korea’s marine, terrestrial, and atmospheric environments, via the continuous and simultaneous multidisciplinary observation of local air and sea environments. Socheongcho ORS is located in the central Yellow Sea about 50 km off the western coast of the Korean Peninsula. Its steel-jacket framed tower-type platform was built near the submarine rock named “Socheongcho” by the Korea Institute of Ocean Science and Technology (KIOST). The Korea Hydrographic and Oceanographic Agency (KHOA) has operated this platform since January 1, 2016. Socheongcho ORS stands 42 m in height above the datum level (DL) and consists of a boat landing plus 7 decks (Bottom Deck, Intermediate Deck, Cellar Deck, Accommodation Deck, Main Deck, Roof Deck, and Heli Deck). Most of its meteorological instruments and sensors are installed on the Roof Deck, including two anemometers, two barometer, two air temperature sensors, and two relative humidity sensors. Ocean temperature and salinity have been relatively consistently measured at Socheongcho ORS. Aanderaa inductive-type conductivity-temperature (CT) sensors are installed at depths of 5.5 m throughout the entire year, operating at 1 min sampling intervals by KHOA. Residential facilities are on the Accommodation Deck and the electrical control room are on the Main Deck, while a seawater desalination system and a diesel generator system are installed on the Cellar Deck.
