متن کاملMiocene to recent eolian dust record from the Southwest Pacific Ocean at 40° S latitude
A 14-meter long pelagic clay core recovered at Marlin Rise (40°00.531′S, 154°2.601′W; 4775 m water depth) in the Southwest Pacific Basin contains a record of eolian dust deposited since the early Miocene. Downcore analysis of detrital minerals reveals a dominantly eolian signature with relatively constant proportions of quartz, feldspar and illite and trace amounts of chlorite, kaolinite and sm...
متن کاملNorth Pacific Climate Response to Freshwater Forcing in the Subarctic North Atlantic: Oceanic and Atmospheric Pathways
Sudden changes of the Atlantic meridional overturning circulation (AMOC) are believed to have caused large, abrupt climate changes over many parts of the globe during the last glacial and deglacial period. This study investigates the mechanisms by which a large freshwater input to the subarctic North Atlantic and an attendant rapid weakening of the AMOC influence North Pacific climate by analyz...
متن کاملGlacial/interglacial changes in subarctic north pacific stratification.
Since the first evidence of low algal productivity during ice ages in the Antarctic Zone of the Southern Ocean was discovered, there has been debate as to whether it was associated with increased polar ocean stratification or with sea-ice cover, shortening the productive season. The sediment concentration of biogenic barium at Ocean Drilling Program site 882 indicates low algal productivity dur...
متن کاملMicrobial Biomass In the Euphotic Zone of the North Pacific Subarctic Water
Microbiological investigations were made in the No rth Pacific subarctic water during spring of 1969. Total bacteria, heterotrophic bacteria, yeasts, and glucose uptake by microorganisms were measured in the euphotic zone. There was no heterogeneity in the distribution of microbial biomasses between Alaskan Gyre, mid-Pacific transitional water, and Western Gyre. Another statistical analysis sho...
