Drifting buoys

INSTRUMENTED BUOYS | DRIFTING BUOYS | SPECIFIC INSTRUMENTED STATIONS

nke Instrumentation develops, manufactures and sells drifted buoys in order to monitor the current at sea surface for oceanographic studies and also the oil spill trajectories. The drifters can be fitted with holey socks drogue and are by this way linked to a particular mass of water. The drag ratio between surface buoy and the drogue validates the good function of current follower. The SC40 buoy can support several sensors such as a Sea Surface Temperature sensor (SST), a Barometric Pressure sensor, a Drogue Presence sensor, a High Resolution Sea Surface Temperature sensor (HRSST) or a Probe sensor Conductivity/Temperature (CT).

SC40: SVP drifter

Description - The SC40 drifters are used mostly in offshore in order to monitor the current at sea surface for oceanographic studies and also the oil spill trajectories. The drifters can be fitted with holey socks drogue and are linked to a particular mass of water. The drag ratio between surface buoy and the drogue validates the good function of current follower. If no drogue is mounted, the drifter is affected by the surface current.

The SC40 buoy is a sphere of 400 mm diameter, molded in plastic at high pressure. The SC40 is equipped with low radar echo in order to reduce the risk to be picked up by fishermen and it is fitted with lashing rings.

SC40 – SVP BRST: Sea surface temperature and depth measurement

Description - The SC40 – SVP BRST buoy is a drifting buoy fitted with a Sea Surface Temperature sensor (SST), a Barometric Pressure sensor, a Drogue presence sensor, a High Resolution Sea Surface Temperature sensor (HRSST), a GPS positioning and an IRIDIUM satellite communication to transmit its data. The sensor can be easily removed from the buoy to be calibrated by any certified metrology laboratory.

This product was developed within requirements of the Data Buoy Cooperation Panel (DBCP), the data buoy component of the Joint World Meteorological Organization (WMO) and Intergovernmental Oceanographic Commission (IOC of UNESCO) Technical Commission for Oceanography and Marine Meteorology (JCOMM).

PCO2 CARIOCA Buoy

Description - CARIOCA is an automatic drifting buoy designed to measure the concentration of pCO2 at the surface of the ocean in order to qualify the CO2 exchange between atmosphere and ocean.

Moreover, to enable correlation the buoy is fitted with sea surface temperature (SST), practical salinity, fluorescence and dissolved oxygen measurements.

It also includes ARGOS transmission equipment and power supply to achieve one year of operating autonomy with measurements every hour.

The body of the CARIOCA buoy consists of a tube (0.20m in diameter and 2.5m in length). A wider yellow floating body surrounds the upper part of the tube. The total weight of the buoy is about 130 kg.
