Question

1. The continental shelf off Virginia and North Carolina is roughly 70 km wide and 310 km long. During the summer, the average daily irradiance over this region is 250 Watts per square meter. Assume that the surface mixed layer is 10 meters deep on average and that 25 percent of the heat is absorbed and retained in this layer. After 30 days, how much warmer (temperature increase) will the surface mixed layer be? (30 points) Remember: Q = c m ΔT Q = heat (joules) m = mass (gram) ΔT = change in temperature (°C) c = specific heat of water = 4.186 J/g/°C 1 Watt = 1 joule/sec density of seawater = 1025 kg/m3 or 1.025 g/cm3 PLEASE SHOW WORK NEATLY!
