Ferrybox

A FerryBox is a continous monitoring system for near surface water. Water is pumped through an inlet on the side/bottom of the ship hull and flows through a tubing system leading to sensors for salinity, temperature, oxygen, particles, Chl a, Phycocyanin and CDOM, pCO2 and pH, before it goes out through an outlet. Simultanous sampling at predefined stations can be done using automatic samplers for water and contaminants. The sensors are quality controlled at minimum every 2 weeks and data are delayed mode biofouling-corrected and calibrated before reporting. The FerryBoxes in operation are MS Color Fantasy (Oslo-Kiel), MS Hurtigruten Trollfjord (Bergen -Kirkenes), MS Norbjørn (Tromsø-Longyearbyen-Ny-Ålesund)

The sensors are quality controlled at minimum every 2 weeks and data are delayed mode biofouling-corrected and calibrated before reporting. The FerryBoxes in operation are MS Color Fantasy (Oslo-Kiel), MS Hurtigruten Trollfjord (Bergen -Kirkenes), MS Norbjørn (Tromsø-Longyearbyen-Ny-Ålesund).

Fluorescence correlation 2015

Color Fantasy Chlorophyll a fluorescence data from 2015 showing very good correlation with Chl a concentration from water samples. This correlation are used in the quality control of the sensor dataas well as making and yearly calibration of the sensor.

Massive Autumn Bloom

A massive bloom was detected in October in the Oslofjord (>14 µg Chl a/L). NIVA first spotted it using FerryBox, and the high concentrations are now confirmed by laboratory analysis.

Report for the Inner Oslofjord Monitoring

Read the technical report (in Norwegian) for the inner Oslofjord monitoring in 2014. The work was done on contract from the municipalities surrounding the fjord. The monitoring includes physical, chemical and biological conditions in the fjord, and some samples were done using FerryBox.
