| We present here a unique oceanographic and meteorological dataset focus on the deep convection processes. Our results are essentially based on in situ data (mooring, research vessel, glider, and profiling float) collected from a multi-platform and integrated monitoring system (MOOSE: Mediterranean Ocean Observing System on Environment), which monitored continuously the northwestern Mediterranean Sea since 2007, and in particular high-frequency potential temperature, salinity and current measurements from the mooring LION located within the convection region. From 2009 to 2013, the mixed layer depth reaches the seabed, at a depth of 2330m, in February. Then, the violent vertical mixing of the whole water column lasts between 9 and 12 days setting up the... |

| The physical context for ocean margin exchange at Goban Spur is described. Observations adjacent to, prior to and during the Ocean Margin EXchange (OMEX) project of 1993-1996 are used. They include currents measured on moorings, drogued-buoy tracks; temperature and other data from CTD profiles, especially as indicators of vertical mixing; evidence from models, particularly for turbulence causing vertical mixing. These data are combined in estimates of (seasonally dependent) mean flow, tidal currents, other current variability, exchange and mixing over the main cross-slope section studied in OMEX and in nearby and contrasted locations (aided by the use of earlier and adjacent measurements). Causative physical processes are discussed: potentially northward... |

| In the ocean outside areas of dense-water formation, coherent vertical motions (w) are generally much weaker (similar to 10(-3)) than horizontal (u, v) ones. According to theoretical models based upon "the traditional approximation", i.e. where the horizontal component of the Coriolis force is neglected, describing inertio-gravity waves in the ocean interior, this holds especially for motions at the inertial frequency f: w(f) < O(10(-2)(u(f), v(f))). We present observations of significant w(f), with mean values of 10(-1)(u(f), v(f)) and occasional values of 1(u(f), v(f)), from the deep Western Mediterranean Sea characterized by very small buoyancy frequency N = 0 +/- 0.4f. Our observations also present evidence of vertical propagation of internal waves,... |

| The macrobenthic faunal composition, sedimentology and physical characteristics were investigated in an open coastal area of the Greek Ionian Sea. Hydrographic parameters were recorded at 26 stations using a CTD profiler during nine cruises performed between 1990 and 1991, while benthic samples were collected in November 1990 and April 1991 at 22 stations with the aid of a Ponar grab. Macrobenthic variety indicated an area of high scientific interest : 351 species in all, 18 of which are new to the Creek fauna. Furthermore, 10 species are previously unrecorded in the Eastern Mediterranean. Of the biological indices estimated, species richness was comparable to that of other open Greek areas, while population density seemed to be a function of a) depth and... |

| The role ships play in atmospheric, oceanic, and biogeochemical observations is described with a focus on measurements made near the ocean surface. Ships include merchant and research vessels; cruise liners and ferries; fishing vessels; coast guard, military, and other government-operated ships; yachts; and a growing fleet of automated surface vessels. The present capabilities of ships to measure essential climate/ocean variables and the requirements from a broad community to address operational, commercial, and scientific needs are described. The authors provide a vision to expand observations needed from ships to understand and forecast the exchanges across the ocean–atmosphere interface. The vision addresses (1) recruiting vessels to improve both... |

| Marine-mammals data management team. |
| The instrumented sea-mammals program is the global network of open-ocean in-situ observations, being implemented by an international partnership of researchers. Instrumented sea-mammals provide trajectories and vertical profiles of various physical, biogeochemical variables in different regions around the globe. The program’s objective is to build and maintain a multidisciplinary global network for a broad range of research and operational applications including biology, climate and ecosystem variability and forecasting and ocean state validation. Sea-mammals data are publicly available. More information about the project is available at: http://www.coriolis.eu.org/Observing-the-Ocean/Marine-Mammals The main purpose of this document is to specify the... |

| The space-borne measurements of the SMOS mission reveal for the first time the complete features of the sea surface salinity (SSS) signature at the full scale of the Pacific basin. The SSS field in the equatorial cold tongue is typically found to be larger than 35.1 within a narrow 2° band of latitude that is positioned slightly south of the equator and that stretches across the eastern Pacific basin up to the Galapagos Islands. On the northern edge of the eastern equatorial Pacific this signature results in a very strong horizontal gradient (larger than 2 units over 100 km) with the fresh waters of the Panama warm pool. By considering a water density criterion, it can be shown that the cold tongue is characterized by a strong seasonal cycle with a 3°C... |

| Previous versions of this document and up to version 2.5 were generated during MyOcean, MyOcean2 and MyOceanFO EU-projects. Starting in CMEMS, several updates have been performed but not officially released. Version 3.1 is the first official release within CMEMS with focus on chlorophyll-a fluorescence. The present Version 6 is the method used for the production of CMEMS INSITU_GLO_BGC_REP_OBSERVATIONS_013_046 release for the V4 of CMEMS in 2018. This document presents quality assessment tools that can be applied as soon as data are delivered to the CMEMS production units, as well as reprocessing tools. The latter requires a certain knowledge about the type and structure of the data in order to build the control quality test. In addition, a set of tools... |

| With the construction of operational oceanography systems, the need for real-time has become more and more important. A lot of work had been done in the past, within National Data Centres (NODC) and International Oceanographic Data and Information Exchange (IODE) to standardise delayed mode quality control procedures. Concerning such quality control procedures applicable in real-time (within hours to a maximum of a week from acquisition), which means automatically, some recommendations were set up for physical parameters but mainly within projects without consolidation with other initiatives. During the past ten years the EuroGOOS community has been working on such procedures within international programs such as Argo, OceanSites or GOSUD, or within EC... |

| Un resumen de datos meteorológicos e hidrológicos para la Bahía de Santa Marta, Caribe colombiano. Se presentan datos de precipitación, temperatura y salinidad del agua superficial para la Bahía de Santa Marta, Caribe colombiano, para el periodo de noviembre 1978 a mayo 1982. Se obtienen generalizaciones de los patrones anuales incluyendo datos ya publicados (Muller, 1979). A partir de mediciones adicionales de la variación de la temperatura del agua y de la salinidad durante el día, valores preliminares de cuantos de luz, junto con datos disponibles sobre contenido y saturación de oxigeno, pH, alcalinidad, estabilidad, dirección y velocidad del viento, horas de luz, temperatura del aire y descarga del Río Manzanares, se hace una caracterización... |

| Parámetros físicos tales como: temperatura, salinidad y velocidad geostrófica han sido estudiados en conjunto para realizar un análisis de la estructura de la Corriente de Cromwell (Subcorriente Ecuatorial), entre 92° 30' W y 84° 30' W y entre las latitudes de 1°N y 4°S, para épocas normales y anómalas como la ocurrida durante el evento de El Niño 82-83. Los valores de velocidad fueron obtenidos usando el método de Montgomery (método indirecto), el cual permite calcular velocidades geostróficas en latitudes bajas. Los resultados conseguidos con este método muestran la presencia de la Subcorriente Ecuatorial, concluyéndose que la metodología aplicada es confiable. Sin embargo, cuando se trata de épocas anómalas como en el caso de "El Niño", los altos... |
