Radium isotopes to investigate the water mass pathways on the Kerguelen Plateau (Southern Ocean)
Natural iron fertilization promotes the phytoplankton bloom that takes place on the Kerguelen Plateau in the Indian sector of the Southern Ocean. We measured Ra (T1/2 1⁄4 5.75 yr) and Ra (T1/2 1⁄4 1602 yr) in waters above the Kerguelen Plateau in order to provide information on the water-mass pathways, which in turn could help elucidate the mechanisms controlling iron fertilization in that area...
متن کاملGlimpses of Arctic Ocean shelf–basin interaction from submarine- borne radium sampling
Evidence of shelf-water transfer from temperature, salinity, and Ra/Ra sampling from the nuclear submarine USS L. Mendel Rivers SCICEX cruise in October, 2000 demonstrates the heterogeneity of the Arctic Ocean with respect to halocline ventilation. This likely reflects both time-dependent events on the shelves and the variety of dispersal mechanisms within the ocean, including boundary currents...

متن کاملIncreasing river discharge to the Arctic Ocean.
Synthesis of river-monitoring data reveals that the average annual discharge of fresh water from the six largest Eurasian rivers to the Arctic Ocean increased by 7% from 1936 to 1999. The average annual rate of increase was 2.0 +/- 0.7 cubic kilometers per year. Consequently, average annual discharge from the six rivers is now about 128 cubic kilometers per year greater than it was when routine...
متن کاملThe Water Cycle across Scales
AMERICAN METEOROLOGICAL SOCIETY | 1743 T he transport and transformations of water substance in the global water cycle are of fundamental and primary importance for understanding the ecosystems, the land surface hydrology that supports them, and the management of water resources for humans. Th e water cycle is also critical for predicting weather, and the long-term climate balance of the planet...
