| The Global Ocean Ship-based Hydrographic Investigations Program (GO-SHIP) brings together scientists with interests in physical oceanography, the carbon cycle, marine biogeochemistry and ecosystems, and other users and collectors of ocean interior data to develop a sustained global network of hydrographic sections as part of the Global Ocean Climate Observing System. A series of manuals and guidelines are being produced by GO-SHIP which update those developed by the World Ocean Circulation Experiment (WOCE) in the early 1990s. Analysis of the data collected in WOCE suggests that improvements are needed in the collection of nutrient data if they are to be used for determining change within the ocean interior. Production of this manual is timely as it... |

| A meeting of the joint IOC-ICES Study Group on Nutrient Standards (SGONS) was held in Paris, France on 23-24 March 2010. It focused on the ongoing activities of the SGONS and plans for extended international collaborations to establish global comparability of the nutrient data from the world’s ocean. Thirty two scientists and experts from 11 countries and 2 delegates from IOC attended the meeting. The discussions followed the Terms of References of SGONS established in July 2009. Development of the reference materials for nutrients in seawater (RMNS) were also discussed in collaboration with the producers. The background and history of SGONS and an international nutrients scale system INSS and the progress with the production of RMNS materials and their... |

| The nature of the physical regime in the vicinity of the Rhine ROFI (Region Of Freshwater Influence) has been determined in a series of collaborative observations. Extensive surveys with shipboard CTD/rosette systems have been used to complement time series observations by an array of moorings instrumented with currentmeters, transmissometers and fluorimeters. The observations reveal a highly variable system in which the influence of the freshwater input from the Rhine extends northeastwards from the source and out to 30 km from the coast. The mean flow within this region is generally parallel to the coast (northeastwards) and with surface speeds, determined by the HF radar, of 15-20 cm.s-1. The residual current at sub-tidal frequencies was strongly... |

| Low salinity (< 35) surface waters (LSSW) at the southern entrance to the western English Channel (48.5 degrees N, 5.1 degrees W, near Ushant) were observed in late winter (March-April) in three successive years (2002-04) during near continuous ship of opportunity operations. The source of the LSSW is the northward spreading plumes from the Loire (47.5 degrees N, 2.5 degrees W) and Gironde (45.6 degrees N, 1.2 degrees W) along the French Atlantic coast. Fastest plume travel times were associated with northeasterly winds, consistent with Ekman theory. Differences between years in the mean winter (January-March) combined river discharges (D) was consistent with the minimum salinities (S-min) of the LSSW (2004: D = 4211 m(3) s(-1), S-min = 33.68; 2003: D =... |
