SNO MEMO - Marine mammal, sample-taker of the marine environment
The SNO-MEMO is an observation network dedicated to the Southern Ocean. Data are collected from in situ Argos beacon sensors placed on the heads of marine mammals : temperature, salinity, fluorescence, light attenuation, dissolved oxygen, prey capture attempts, sea state.
The Southern Ocean plays a fundamental role in the regulation of our planet's climate. This ocean hosts an ecosystem that is likely to be very vulnerable to global warming, as many species of phytoplankton and zooplankton are very dependent of the Antarctic sea ice. The SNO-MEMO allows to cover the Indian sector of the Southern Ocean. With other international partners, a quasi synoptic coverage of the Southern Ocean is ensured.

The SNO-MEMO is an observation network dedicated to the Southern Ocean. Data are collected from in situ Argos beacon sensors placed on the heads of marine mammals : temperature, salinity, fluorescence, light attenuation, dissolved oxygen, prey capture attempts, sea state.
The Southern Ocean plays a fundamental role in the regulation of our planet's climate. This ocean hosts an ecosystem that is likely to be very vulnerable to global warming, as many species of phytoplankton and zooplankton are very dependent of the Antarctic sea ice. The SNO-MEMO allows to cover the Indian sector of the Southern Ocean. With other international partners, a quasi synoptic coverage of the Southern Ocean is ensured.

Data files in NetCDF4 (CF1.7) format can be downloaded from the authenticated CEBC FTP server or directly from this metadata sheet. For a download through the CEBC and a request for specific data preparation, use the contact (Baptiste Picard) displayed on this metadata sheet.
The filenames on the download server display the following nomenclature: DeploymentName / DeploymentName_IndividualName_DeploymentYear_Resolution.
The catalog allows the display of elephant seal trajectories: click on Data Access > "View" and open the "Map" tab. The trajectories can be displayed on this map according to 3 types of filters: deployment name (type "ct112" for example), variables (temperature, salinity, chlorophyll, oxygen) and dates.
It is thus possible to visualize the trajectories selected according to these filters. A click on a point of one of the trajectories finally gives the name of the deployment of the individual and the date. Example: ct112-047-14.
From the name of the deployment ("ct112" in this example), the data files of this individual are directly downloadable in the ct112 directory.
Any use of this dataset must cite its DOI (https://doi.org/10.12770/8c8c52b3-4b00-4d11-9dad-37edf6395d82) and the following sentence: This work is supported by CNRS/INEE, CNES, IPEV, IMOS (Integrating Marine Observation System), OASU, Coriolis.

The SNO-MEMO is one of the components, labelled by INSU, together with the SO Pirata, ARGO and SSS of SOERE CTD-O2 (Long-term observation and experimentation system for environmental research CORIOLIS Differed Time Ocean Observations).
SNO-MEMO is the French contribution to the international project MEOP (Marine Mammals Exploring the Oceans Pole to Pole), whose temperature and salinity data are integrated into this international database. Thus, compared to the MEOP database, the SNO-MEMO dataset integrates very high frequency data of several additional variables.
The deployment campaigns take place on land, just after the breeding and moulting periods of these marine mammals, respectively, in October-November and January-February on the Kerguelen Archipelago and on the Valdez Peninsula in Argentina. The journeys of these mammals in the open ocean can last from 2 months for the post-reproduction periods, up to 8 months for the post-molt periods.
In the case of the elephant seal "mirounga leonina", the measurement profiles regularly descend between 500 m and 1200 m depth and up to 2000 m maximum, to areas very far from Kerguelen, in waters rich in prey, close to the Antarctic continent, sometimes even under the sea ice.
The real-time raw data, transmitted by satellite at each return to the surface of the animal, are collected at the CDS-IS-Coriolis.
All the data are collected when the animal returns to land, when the beacons are recovered. These high frequency data are then analyzed and a precise diagnosis of the quality of the data is established. These delayed-time data are updated every 18 months or so.
