Not exact matches

For 30 million years, beginning 530 million years ago, the oxygen levels of the ocean dropped steadily, four different sets of chemical measurements suggested.

However, measurements show that this is not the case even in the large and essentially anoxic oxygen minimum zones of the tropical oceans.

The work has implications for how ocean modelers determine the overall amounts of carbon dioxide taken up by the oceans, which is typically performed through oxygen - based measurements.

Britton Stephens, an NCAR scientist and the project's co-principal investigator, said HIPPO flights have collected the first large - scale measurements of carbon dioxide and oxygen cycling into and out of surface waters of the Southern Ocean.

Based on oxygen (and d13C) measurements, we have a rough indication which one takes the most: about 1 / 3rd of the total sink is going into the biosphere, 2 / 3rd into the oceans.

More exact for the partitioning between oceans and vegetation are found in the oxygen balance, but with large margins of error, as oxygen change measurements (a few ppmv in 200,000 ppmv) are extremely difficult, at the edge of the accuracy of the methods used.

Facilitated by the invention of an elegant and precise wet - chemical method by Winkler (1888), which has remained essentially unchanged until today, reliable and comparable oxygen measurements have been made during innumerable research cruises to all parts of world ocean such that a detailed picture of the distribution of oxygen has emerged long since.

«From our measurements, we estimated that the oxygen consumption within the eddies is some five times larger than in normal ocean conditions,» Karstensen explained.
