You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: the authors confirm that all data underlying the findings are fully available without restriction. we used daily 4-km, version 5 advanced very high resolution radiometer pathfinder sst (19822012) available at http://www.nodc.noaa.gov/sog/pathfinder4km/. chl data were taken from the national aeronautics and space administration's daily 4-km level-3 moderate resolution imaging spectroradiometer daily data set (20022010) available at http://oceancolor.gsfc.nasa.gov/. we extracted weekly 1/3° (i.e., about 33 km at these latitudes) ssalto/duacs sea level anomalies and geostrophic velocity anomalies (u,v) computed and distributed by aviso (19922012), with support from the centre national d'études spatiales (http://www.aviso.oceanobs.com/duacs/). the bathymetry of the mediterranean basin was extracted from the etopo1 database hosted on the national oceanic and atmospheric administration's website at ~4 km resolution using the getnoaa.bathy function (marmap package, http://cran.r-project.org/).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
