The US Geological Survey says it’s estimated oceans store 1,338,000,000 cubic kilometers (321,000,000 cubic miles) of the world’s water supply. But we tend to use fresh surface water from rivers – where we can. Other great depths include the Puerto Rico Trench in the Atlantic, the Java Trench in the Indian ocean, and the Arctic Basin. The US Environmental Protection Agency reports an average steady increase in sea surface temperatures since 1880. Rising sea surface temperatures are taken as an indicator of climate change.
