KEY Test 3 (2014), Physics Long Answer
1. (VERSION A and C) During the winter monsoon season, winds blow from the Northeast
along the Southeast coast of Oman. Wind speeds during the winter average around 5 m s-1.
On the map, draw a single arrow showing
Wind stress on the ocean can be approximated as
= a cW 2
where a = 1 kg m3 is the density of air, c 2 103 is the drag coecient and W is the
wind speed. A typical wind is 7.4 m s1 . Therefore
= 1 kg m3 2 103 (7.4 m s1 )2
= 0.110 kg m1 s2

living at 75 m depth in the tropics,
will most likely have ?
Chlorophyll a & phycocyanin
Chlorophyll b & phycocyanin
Chlorophyll a & phycoerythrin
Chlorophyll b & carotenoids
We are all familiar with seawater. We know that compared to most continental
waters (rivers, most lakes, groundwater), it is salty. By this we mean that it
contains a relatively large amount of dissolved solids, which we generally call
