Bioavailability of dissolved organic phosphorus in the euphotic zone at Station ALOHA, North Pacific Subtropical Gyre
The biologically available phosphorus (BAP) and soluble reactive phosphorus (SRP) concentrations and phosphorus (P) uptake rates within the euphotic zone (0–175 m) were measured on eight cruises between October 2000 and November 2001 to Sta. ALOHA (22.758N, 1588W) in the North Pacific Subtropical Gyre. The SRP concentrations in the upper 100 m ranged from 7 to 84 nmol P L21, with a mean concent...
متن کاملSeawater of the Euphotic Zone
Microbial biomass on suspended organic matter in seawater of the euphotic zone of Saanich Inlet was investigated. The viable microorganisms were measured by the glucose-uptake method. Microbial carbon on particulate organic matter in seawater was determined to be, on the average, 9.9 ,ug of C/liter, and there was a regression relationship as y = 0.0062 x 1.79 with an unbiased variance Vyx12= 0....
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...
متن کاملListening for Whales at the Station ALOHA Cabled Observatory
The Station ALOHA Cabled Observatory (ACO) is an ocean-bottom observatory that allows continuous real-time monitoring of ocean processes including sounds produced by baleen whales. Baleen whales can be challenging to study using traditional visual methods due to their cryptic behavior and offshore ranges. Many baleen whales produce distinctive sounds that propagate well under water and so ocean...
متن کاملQuantification of methylphosphonate associated to suspended material at Station ALOHA
Methylphosphonate (MPn) metabolism has been proposed to be an aerobic source of methane in surface oceanic waters. Previous work by Daniela del Valle, C-MORE post-doctoral fellow in the laboratory of Prof. David Karl, has shown that even though microbes are able produce methane from dissolved MPn in the ocean, this process is not a significant source of methane at Station ALOHA. However, this w...
