Sir James Ross
Took the earliest depth measurements
study sea floor sediments, plate tectonics, history of the earth and atmosphere
study chemical composition of the oceans and their relationships to geology and biology.
explored the Mediterranean and Atlantic-noticed a current running in and out. named it "okeanos" ocean was derived from this.
First Library of Alexandria
contained written info on items of interest to seafarers. All ships that entered the harbor were recorded and a copy of records was kept there.
during the dark ages they wet on periodic raids. ships were so fast they could sail up rivers
discovered the New world by accident. The native Americans had lived there for at least 11,000 years.
studied ship's logs with wind and temp data. assembled it into wind and current charts & issued them to sailors for giving him their logs when they returned.
Charles Thomson and John Murray led first scientific oceanographic voyage. 4 yrs. thought they was no life below 1,800ft. able to sample down to 26,850ft. found 4,717 new species. took 15 yrs. to produce the "Challenger Report" 50 volume report.
study how to build ocean going to vessels, harbors, oil platforms, etc.
