Chlorophyll-a and Phytoplankton Community Observations from Euphotic Zone...
Chlorophyll-a concentrations were measured as an indicator of primary productivity within the euphotic zone, covering standard sampling depths from the surface down to 200 m. In... -
CTD Hydrographic and Biogeochemical Observations Using Sea-Bird SBE 911plus...
This dataset contains hydrographic and biogeochemical observations collected during an oceanographic survey in Madagascar using Conductivity–Temperature–Depth (CTD) profiling... -
Microplastics Distribution in Surface Waters from Continuous Underway Fish...
Microplastics were collected using he Continuous Underway Fish Egg Sampler (CUFES). The CUFES system provided continuous underway sampling of near-surface waters, enabling high-... -
Shipborne Multifrequency Echo Sounder and Multibeam Data for Fisheries and...
This dataset contains active acoustic observations acquired using a Simrad EK80 Scientific Split-Beam Echo Sounder with keel-mounted transducers operating at 18, 38, 70, 120,... -
Surface Ocean Physical and Bio-Optical Measurements from Shipborne SBE 21...
A Sea-Bird SBE 21 SeaCAT Thermosalinograph (TSG) operated continuously throughout the survey, drawing seawater from a hull intake at 4 m depth and recording salinity,... -
Demersal and Pelagic Trawl Survey Dataset for Fish Community Composition,...
A total of 82 trawl stations were conducted during the survey, comprising 74 demersal trawls and 8 pelagic trawls across a depth range of 26 to 777 m. Of these, eight stations... -
Surface Neuston Dataset of Fish Larvae and Microplastics from Manta Trawl...
A Manta trawl equipped with a 335 µm mesh size was deployed outside the vessel wake and towed at a speed of 2–3 knots (approximately 1.5 m/s) for 15 minutes at all super-... -
Vertical Net Haul Observations of Zooplankton Biomass and Composition Using WP2
Zooplankton samples were collected using vertical hauls of a WP2 plankton net (56 cm mouth diameter, 180 µm mesh size) at a retrieval speed of approximately 0.5 m s⁻¹. Tows were... -
Ichthyoplankton Community and Genetic Dataset Collected Using Bongo Net (405...
Ichthyoplankton samples were collected using a Bongo net with a 405 µm mesh size. The samples are intended for ichthyoplankton community identification and genetic analysis,... -
Vessel-Mounted ADCP Observations of Ocean Currents with Motion-Corrected...
Ocean current data were collected using a vessel-mounted Teledyne RDI Ocean Surveyor Acoustic Doppler Current Profiler (ADCP) operating at 150 kHz. Vessel motion and navigation...
