The two major resources mined at sea include oil and minerals. Over the last 30 years, deep-sea mining has generated between $9 -$11 billion USD in the United States of America. [43] [44] Although this sector seems profitable, it is a high risk, high reward industry with many harmful environmental impacts. [45]
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase , in which case it is also known as a tidal datum . [ 1 ]
Sea State 5 and 8 range. In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum. The sea state varies with time, as the wind and swell ...
The Douglas sea scale is a scale which measures the height of the waves and also measures the swell of the sea. The scale is very simple to follow and is expressed in one of 10 degrees. The scale is very simple to follow and is expressed in one of 10 degrees.
Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 200 millimetres (7.9 in) during the 20th century (2 mm/year). Precise determination of a "mean sea level" is difficult because of the many factors that affect sea level. [6]

By the 2010s, Greenland was contributing roughly 0.8 mm/yr to sea level rise, and Antarctica was contributing roughly 0.4 mm/yr, both accelerating by 10%/yr (a doubling time of 7 years). [citation needed] Climate models estimate they will contribute 1 m - 2 m to sea level rise by 2100, mostly in the latter half of the century [10] [11]
