Observations of open-ocean deep convection in the northwestern Mediterranean Sea: Seasonal and interannual variability of mixing and deep water masses for the 2007–2013 period ArchiMer
Houpert, L.; Durrieu De Madron, X. Durrieu; Testor, P.; Bosse, A.; D'Ortenzio, F.; Bouin, M. N.; Dausse, D.; Le Goff, H.; Kunesch, S.; Labaste, M.; Coppola, L.; Mortier, L.; Raimbault, P..
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...

Climate Change-Induced Emergence of Novel Biogeochemical Provinces ArchiMer
Reygondeau, Gabriel; Cheung, William W. L.; Wabnitz, Colette C. C.; Lam, Vicky W. Y.; Frölicher, Thomas; Maury, Olivier.
The global ocean is commonly partitioned into 4 biomes subdivided into 56 biogeochemical provinces (BGCPs) following the accepted division proposed by Longhurst in 1998. Each province corresponds to a unique regional environment that shapes biodiversity and constrains ecosystem structure and functions. Biogeochemical provinces are dynamic entities that change their spatial extent and position with climate and are expected to be perturbated in the near future by global climate change. Here, we characterize the changes in spatial distribution of BGCPs from 1950 to 2100 using three earth system models under two representative concentration pathways (RCP 2.6 and 8.5). We project a reorganization of the current distribution of BGCPs driven mostly by a poleward...

Smith, Shawn R.; Alory, Gaël; Andersson, Axel; Asher, William; Baker, Alex; Berry, David I.; Drushka, Kyla; Figurskey, Darin; Freeman, Eric; Holthus, Paul; Jickells, Tim; Kleta, Henry; Kent, Elizabeth C.; Kolodziejczyk, Nicolas; Kramp, Martin; Loh, Zoe; Poli, Paul; Schuster, Ute; Steventon, Emma; Swart, Sebastiaan; Tarasova, Oksana; Petit De La Villeon, Loic; Vinogradova-shiffer, Nadya.
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...

Gyroscopic waves in the Mediterranean Sea ArchiMer
Van Haren, Hans; Millot, Claude.
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,...

Recommendations for in-situ data Near Real Time Quality Control ArchiMer
EuroGOOS DATA-MEQ working group.
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...

Physical structures, advection and mixing in the region of Goban spur ArchiMer
Huthnance, John M.; Coelho, Henrique; Griffiths, Colin R.; Knight, Philip J.; Rees, Andrew P.; Sinha, Bablu; Vangriesheim, Annick; White, Martin; Chatwin, Paul G..
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...

Oceanologic study of an open coastal area in the Ionian sea with emphasis on its benthic fauna and some zoogeographical remarks ArchiMer
Zenetos, A; Christianidis, S; Pancucci, Ma; Simboura, N; Tziavos, C.
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 salinity signature of the equatorial Pacific cold tongue as revealed by the satellite SMOS mission ArchiMer
Maes, Christophe; Reul, Nicolas; Behringer, David; O'Kane, Terence.
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...

Heat and salt storages in the offshore water of the Red Sea OceanDocs
Kamel, M.S.; Eid, F.M..
The seasonal changes of heat and salt storages in the offshore water of the Red Sea were studied using a historical data collected from different cruises during the period from 1924 to 1998. The heat storage within water column of different depths exhibits a seasonal variability. The heat storage is low during winter and high during summer. Also, the heat storage increases from north to south. The maximum values of heat storage are found in the southern central part of the Red Sea. It reached about 29.9x109 J/m2 within the water column of 300m depth. The seasonal change of heat storage from the annual mean is negative during winter and spring, while it is positive during summer and autumn. It has higher values during winter and summer, while its value...
