Proposed
working schedule on R/V Poseidon cruise POS 330
Las
Palmas - Las Palmas (November 20th. to
December 3rd, 2005)
The
main goal of this R/V Poseidon cruise will be the
maintenance of the DOLAN permanent surface buoy,
deployed in 3.600 m water depth 60 nm north of Las
Palmas de Gran Canaria. On the surface buoy itself
several electronic components will be maintained/changed.
It is planned to replace the short distance radio
link by a wireless LAN communication link. In
addition, a new CAN bus interface will be installed
in parallel to the serial RS232 sensor link
(ORBCOMM, 2 x MicroCat TS). The CAN bus interface is
more reliable to communicate over longer distances.
Especially the Nutrient analyzer (NAS) and the
Fluorometer, both deployed at 100 m water depth
below the buoy, shall be implemented into the CAN
telemetry. In addition, another MicroCat will be
implemented at this water depth. Hopefully, starting
after this cruise the online data are accessible via
the ORBCOMM link (0.5 m, 10 m; T,S) and via IRIDIUM
link (100 m; Nutrients, Chlorophyll, T,S) and
weather data (Wind speed, direction, air pressure,
temperature, humidity).
