Hydrography in the Mediterranean Sea during a cruise with RV Poseidon in April 2014
Summary: We report on data from an oceanographic cruise in the Mediterranean in April 2014. Data were taken on a west-east section starting at the Strait of Gibraltar and ending south-east of Crete, as well on sections in the Ionian and Adriatic Sea. The measurements include salinity, temperature, oxygen and currents. We study the mesoscale eddy field and support long-term investigations of the hydrography in the Mediterranean Sea.

Post-Chernobyl surveys of radiocaesium in soil, vegetation, wildlife and fungi in Great Britain
Summary: The data set ‘Post Chernobyl surveys of radiocaesium in soil, vegetation, wildlife and fungi in Great Britain’ was developed to enable data collected by the Natural Environment Research Council after the Chernobyl accident to be made publicly available. Data for samples collected between May 1986 (immediately after Chernobyl) to spring 1997 are freely available for non-commercial use under Open Government Licence terms and conditions. doi: 10.5285/d0a6a8bf-68f0-4935-8b43-4e597c3bf251.

Woodland Survey of Great Britain 1971–2001
Summary: The Woodland Survey of Great Britain is a unique data set, consisting of a detailed range of ecological measurements at a national scale, covering a time span of 30 years. A set of 103 semi-natural woods spread across Britain were first surveyed in 1971, which were again surveyed in 2000-2003. Standardised methods of describing the trees, shrubs, ground flora, soils and general habitats present were used for both sets of surveys.

Perceived temperature in the course of climate change: an analysis of global heat index from 1979 to 2013
Summary: We evaluate global changes to heat index, a measure of perceived temperature. The product is daily means, minima and maxima gridded to 0.75°x0.75° for the entire globe from 1979 to 2013. The results show the uneven distribution in changes in heat index throughout space and time. They can serve as a basis for future studies on the evolution of heat index in climate change and its effects on human society.

Filling the gaps in meteorological continuous data measured at FLUXNET sites with ERA-Interim reanalysis
Summary: In order to fill the gaps in the in situ meteorological data that is acquired at FLUXNET stations, we develop a method that makes use of the reanalysis ERA-interim, which is available globally and at a high temporal resolution. Because the ERA-interim data are not measured at site level, we bias-correct them. The developed method is applied and evaluated at 153 FLUXNET stations. The final product consists of uninterrupted meteorological records that can be used for running most ecosystem models.

CEH-GEAR: 1 km resolution daily and monthly areal rainfall estimates for the UK for hydrological and other applications
Summary: The CEH – Gridded Estimates of Areal Rainfall (CEH–GEAR) dataset contains 1 km gridded estimates of daily and monthly rainfall for Great Britain and Northern Ireland (plus approximately 3000 km2 in the Republic of Ireland) from 1890 to 2012. The rainfall estimates are derived from the Met Office national database of observed precipitation, using a natural neighbour interpolation methodology which includes a normalisation step based on average annual rainfall.

Measurements of the stable carbon isotope composition of dissolved inorganic carbon in the northeastern Atlantic and Nordic Seas during summer 2012
Summary: We present measurements of the stable carbon isotope composition of seawater dissolved inorganic carbon. The samples were collected during two research cruises in boreal summer 2012 in the northeastern Atlantic and Nordic Seas. The results can be used to investigate the marine carbon cycle, providing information about biological productivity and oceanic uptake of anthropogenic carbon dioxide.

A metadata template for ocean acidification data
Summary: With the rapid expansion of studies on biological responses of organisms to OA, the lack of a common metadata template to document the resulting data poses a significant hindrance to effective OA data management efforts. In this paper, we present a metadata template that can be applied to a broad spectrum of OA studies, including those studying the biological responses of organisms to OA. This paper defines best practices for documenting ocean acidification (OA) data.

Data on geochemical and hydraulic properties of a characteristic confined/unconfined aquifer system of the younger Pleistocene in northeast Germany
Summary: The paper presents a database of hydrochemical and hydraulic groundwater measurements of a younger Pleistocene aquifer system in NE Germany. The Leibniz Centre for Agricultural Landscape Research (ZALF) operates seven groundwater monitoring wells in the Quillow catchment located in the Uckermark region (Federal State of Brandenburg, Germany). This database can be used for the investigation of subsurface water geochemistry under changing hydraulic boundary conditions regarding a 14-year period.

Hydrological and meteorological investigations in a periglacial lake catchment near Kangerlussuaq, west Greenland – presentation of a new multi-parameter data set
Summary: This paper presents a hydrological and meteorological data set from the Kangerlussuaq region, western Greenland. The data set is used to conceptualize and model the hydrological system and constitutes an important platform in order to describe the exchange of water between the surface, active layer, the lake, and the underlying talik. The resulting hydrological model will be used as a basis for biogeochemical mass-balance and transport calculations of the terrestrial and limnic ecosystems.

Global carbon budget 2014
Summary: Carbon dioxide (CO2) emissions from human activities (burning fossil fuels and cement production, deforestation and other land-use change) are set to rise again in 2014. This study (updated yearly) makes an accurate assessment of anthropogenic CO2 emissions and their redistribution between the atmosphere, ocean, and terrestrial biosphere in order to better understand the global carbon cycle, support the development of climate policies, and project future climate change.

Mapping hydrological environments in central Amazonia: ground validation and surface model based on SRTM DEM data corrected for deforestation
Summary: This work presents two data sets: a digital elevation model in which deforestation effects were minimized over a large area in Central Amazonia and a set of 18 topographic–hydrological descriptors calculated by the use of the Vertical Distance to the Nearest Drainage algorithm (HAND). We describe the methodology to generate and validate the data sets. Moreover, we present a brief discussion about the applicability of the data to fill the gap of environmental data in Amazonian lowland forests.

A new compilation of stomach content data for commercially important pelagic fish species in the northeast Atlantic
Summary: This work describes a 148-year compilation of stomach content data for five pelagic fish species (herring, blue whiting, mackerel, albacore and bluefin tuna) sampled over a broad geographic region of the northeast Atlantic. We describe the main results in terms of diet composition and predator–prey relationships. The analyses suggests significant differences in the prey items selected by predators in different parts of the area at different times of year.

Lake surface water temperatures of European Alpine lakes (1989–2013) based on the Advanced Very High Resolution Radiometer (AVHRR) 1 km data set
Summary: We were able to demonstrate that data from polar orbiting satellites can be used not only to derive lake water temperature for large lakes (> 500km2) but also for the many lakes like in central Europe which are smaller than 100km2. The linear warming trend derived for one of the lakes shows good agreement between in situ and satellite observations. Thus, this data set will offer the possibility to investigate the impact of climate change on lake water temperatures in central Europe.
