Hourly values of hydrological data in the area of Antikythira strait, produced by a marine mooring deployed by HCMR. The monitoring instruments have been positioned at two depths: a) Close to the bottom (approximately 875 m) and b) At intermediate depth (325 m). The mooring site is found at latitude 35ο 36.8 N and longitude 23o 32.3 E.

Data of hydrological parameters in the water column selected at 11 discrete points in the Cretan and southeast Ionian Sea, during an oceanographic cruise conducted in April 2025 under the CLIMPACT project. Data include pressure, in-situ temperature, potential temperature, salinity, potential density σθ and dissolved oxygen, from surface to bottom. Data were sampled with shipborne CTD probe.

Field samples were collected biweekly from a coastal site in Agios Kosmas, over a 26-year period between November 1988 and April 2015, as well as, with gaps, from June 2015 to June 2018.

Data time-series of ~20 years (1997-2018)of seagrass Posidonia oceanica annual production covering sixty sites across the Greek Seas. For the same time period, annual sea surface temperature and sea surface temperature of August data are also given.

The dataset includes time-series data on the annual production of the seagrass Posidonia oceanica from 2007 to 2021, covering nine sites across the Greek Seas. During the same period, satellite- derive records of annual sea surface temperature, sea surface temperature of summer (average for July to September)and maximum sea surface temperature are also provided.

CALIPSO-based Climate Data Record of Dust Deposition Rate and atmospheric dust over the broader Mediterranean Sea domain for the temporal period between 2007 and 2021.

CALIPSO-based LIVAS Climate Data Record and atmospheric dust over the broader eastern Mediterranean Sea domain for the temporal period between 2006 and 2022.

Total averaged-dry air mole fractions of greenhouse gases for the region of Thessaloniki, such as carbon dioxide, methane, water vapor, carbon monoxide . Measurements were performed using a portable Bruker EM27/SUN spectrometer in the frame of the COllaborative Carbon Column Observing Network (COCCON), which measures direct solar radiation and each spectrum is obtained every 58 seconds, during clear-sky days. Data also include other measured quantities such as: the uncertainty of each measurement (rms), the time of measurement (UTC), the solar zenith ang...

The dataset includes daily meteorological parameters for the period 2010-2023 from 54 meteorological stations. You can see visualizations of the data from these stations on the page https://www.meteo.gr/climate/ The parameters are temperature (°C), relative humidity (%), pressure (hPa), rainfall (mm), wind speed (km/h), dominant wind direction, and wind gust (km/h). The measurements come from the network of automatic meteorological stations of the National Observatory of Athens/meteo.gr. Information about the stations and any malfunctions are prov...
