Figure 7.2. Spatial distribution ofthe absolute wind strength and direction during cruise 0671013-1. Wind 
information is reported on the Beaufort scale (see colour bar) and averaged over 15 min intervals. The 
sfick orientation denotes the wind direction. 
7.2 Thermosalinograph and Fluororescence & Turbidity 
The thermosalinograph (TSG) system aboard RV ATAIR is operated as a throughflow system 
with the pure seawater inlet installed in the vessel’s hull at a depth of 4 m. It consists of a 
SBE21 Seacat thermosalinograph device delivering near-surface conductivity and internal 
temperature measurements that are matched with an additional external temperature sensor 
of type SBE38 located near the water inlet. Next to the TSG system, a dual-wavelength sensor 
of type WET Labs Environmental Characterization Optics (ECO) is installed delivering near- 
surface underway measurements for fluorescence and turbidity. Table 7.1 provides an over- 
view on sensor specifications. Data are recorded at time steps of 10 sec. Data recording was 
switched off when passing through the Ductch EEZ. Swedish authorities demanded to switch 
off logging while transiting through the Swedish territorial waters. Consequently, there are not
