11.3.1 Seasonal summary of offshore oil spill sensitivity<br />

55°W<br />

In relation to this assessment classification of offshore areas is particularly<br />

relevant and this has been updated with the newest available data (Figures<br />

11.3.2). <strong>The</strong> offshore areas were defined on the basis of a cluster analysis in<br />

order to obtain ecol<strong>og</strong>ically meaningful areas, and the four seasons were calculated<br />

separately. <strong>The</strong> cluster analysis included twelve variables: air temperature,<br />

air pressure, sea surface temperature (two different measurements),<br />

temperature at a depth of 30 m, salinity at the surface and at 30 m in<br />

depth, wind speed, ice coverage, sea depth, slope of seabed and distance to<br />

coast (<strong>for</strong> details see Mosbech et al. 2004b).<br />

For each season and offshore area various symbols are shown in Figure<br />

11.3.2 <strong>for</strong> important species or species groups according to their relative<br />

abundance. For each season the relative sensitivity to oil spill is calculated<br />

<strong>for</strong> each offshore area, ranging from low to extreme sensitivity. This classification<br />

is based on the relative abundance of resources, but also species specific<br />

sensitivity values, an oil residency index, a human use factor and a few<br />
