Therefore, in order to realize the objectives of this research, a long-time data record is needed as well as a location that is readily influenced by water mass intrusions. Ocean Weather Station NOVEMBER (OWS N) affords such an oppor- tunity, since it offers both a long period of data and is strategically positioned at the transition zone between the Subarctic and Subtropical water masses. Evidence of subarctic water mass intrusions at Ocean Weather Station NOVEMBER. By John Francis. Pfeiffer and Robert H. Bourke. Topics: Oceanography.

The monthly horizontal thermal advection in the upper m of the water column at ocean weather station (OWS) November was calculated by means of a divergent heat budget equation. temperature and salinity data from ocean weather station No- vember (30øN, øW) to document such southward intru- sions at 7- to 8-month intervals. Records of (a) surface circulation, (b) potential temperature θ at m, (c) potential density at m, and (d) vertical displacement at m during the Ocean Station Papa (OSP) mooring time series. Vertical dashed lines in Figures 17b and 17c indicate the time bounds of the Seaglider surveys at by: 4. The book has also been extensively reorganized to weave issues of Arctic change throughout the text, rather than confining them to a single chapter. It is the first to provide an integrated assessment of the Arctic climate system, recognizing that a true understanding of how the Arctic functions lies in appreciating the interactions among its Cited by:
Eddies with cold and fresh core water are found mainly around the Oyashio southward intrusions and farther north near the Kuril Islands. Based on the heat content anomaly integrated over 50– dbar, 85% of the anticyclonic eddies within the study area (35°–50°N, °–°E) have a warm and saline core and 15% have a cold and fresh by: ANDERSON etal, () documented an annual decrease of surface water nitrate from 13 to 6gM at Ocean Weather Station P during , and a change from 19 to 6 gM in a larger region of the Gulf of Alaska (between 50° and 55°N and ° and °W).Cited by: If a warm and saline water mass in the upper layer of the Kuroshio Extension is shed to the subarctic region and depresses the cold and fresh surface layer downward, then the upper layer becomes warm and saline compared with the ambient waters of the same depth, whereas the depressed layer is cold and by: and September), in which weather conditions and sea ice coverage impeded access to Marguerite Bay and other near-shore areas.
