The ASCA shelf and tall moorings extend 200 km offshore of Hamburg just south of East London on the East coast of South Africa, along the decending TOPEX/Jason satellite ground track # 96, through the core of the Agulhas Current, with Current- and Pressure-recording Inverted Echo Sounders (CPIES) measurements extending the array to 300 km offshore. There are two shelf and seven full-depth tall moorings, interspersed with five CPIES, measuring pressure, current velocities, temperatures and salinities.

The Chalk Karst observatory groups different karst sites on the Cretaceous Chalk located at the Paris Basin (Norville, Radicatel, Yport, Saint-Martin-Le-Nœud). These karst watersheds range from 10 to 200 km2 and the land use consists of agriculture and grazing under oceanic climate. There are characterized by chalk plateaus covered with clay-with-flints owing to chalk weathering constituting a fairly impervious layer and with quaternary silts. These surficial formations range from 3 to 20 meters depth and are highly susceptible to crusting, compaction, and erosion, particularly during autumn and winter. A numerous swallow holes locally penetrates the chalk through the above-mentioned impervious layer, resulting in a strong connection of the surface with the aquifer inducing infiltration of turbidity releases at spring and well used to drinking water (up to 500 NTU). These Chalk karst sites are one the sites of the French SO-KARST labellised by INSU-CNRS and are a part of the French RBV-Network and ZA Seine.

The Northeast US Shelf (NES) ecosystem spans the Middle Atlantic Bight and Gulf of Maine, is a large portion of the NW Atlantic Shelves Province, and is in a coastal biome. The waters over the NES provide an array of ecosystem services including fishing, energy development, shipping, waste disposal, recreation, and conservation. The NES ecosystem, like other productive temperate shelf ecosystems, is characterized by strong seasonality along with high levels of variability in physical forcing at timescales from days to decades, including climate impacts.

The National Institute of Oceanography (IOLR) is located in Haifa (Tel Shikmona) on the shores of the Mediterranean Sea. The institute engages in research and development in marine sciences and provides information and professional advice to the government and the public sector in the context of the sustainable utilization and conservation of Israel’s marine and coastal resources. The oceanographic studies at the institute are engaged in research, monitoring, and collecting environmental data in the Mediterranean Sea, and in studying natural and unnatural processes. The research topics at the institute include subjects such as; flow and mixing processes; oceanographic models; material cycles; sediment transportation and geological processes; the structure of the seabed; physiology, immunology, and ecology of marine organisms and the populations’ dynamics; the biological diversity in offshore waters and deep seas; effects of human activity on the open sea and coastal environment. IOLR operates advanced instruments and national infrastructures for marine research and monitoring, such as; the national research vessel “Bat Galim”, small ships, and autonomous underwater gliders. A variety of mapping, sampling, data collection, and independent systems are placed at sea for continuous monitoring of environmental variables. In addition, ecological monitoring (community structure, biological diversity, etc.) is carried out in several habitats at a monthly to yearly frequency as follows: • Seasonal ecological monitoring of the Benthos community of the vegetation tables in four sites from north to south since 2009 (also includes a monthly sampling of the water - chlorophyll, nutrients, alkalinity, DIC, temp., pH). • Seasonal ecological monitoring of the benthos community (fish, and biotic cover) of the shallow reefs in the Shekmona/Rash Carmel area. • Annual ecological monitoring of the mesophotic reefs (90-100 meters) at the top of Carmel and the shallow reef. • Monthly zooplankton monitoring at the Hadera station • Monitoring the fish society and the invertebrate community in sandy bottoms • Deep sea monitoring IOLR operates the National Marine Information Center - ISRAMAR, which collects, records, and distributes data and information regarding Israel’s marine environment.

The Transetto Senigallia-Susak is a transect of sampling stations located in the Northern Adriatic Sea. The IRBIM-CNR in Ancona and the Politechnical University of Marche collects from the end of years 80s physical, chemical and biological data. This is an excellent observing site to analyze the characteristics of water masses entering and leaving the North Adriatic Sea and their possible modification. In the site is also located the TeleSenigallia pylon.

The basis for the Spiekeroog Coastal Observatory (SCO) was established in 2002 as the Time Series Station Spiekeroog. The Coastal Observatory seized preceding research initiatives and grew continuously to the recent observational infrastructure including a multitude of elements and parameters. Today, the SCO and the conducted research around, improve our understanding of environmental change and anthropogenic impacts on coastal areas along the land-sea interface. The unique characteristic of the SCO can be found within this interdisciplinarity of the element sites operated in the largest tidal flat region worldwide.

The coastal marine observatory site Gulf of Trieste lies within the Marine Protected Area (MPA) of Miramare and includes the biological time-series station “C1”, part of the Italian Long-Term Ecological Research (LTER) network, and the in situ continuous MAMBO meteo-oceanographic buoy. Marine Protected Areas represent one of the most effective systems for marine biodiversity preservation and management. Since 1986, the time-series station “C1” in the Gulf of Trieste (GoTTs, Gulf of Trieste Time series) represents a crucial site for marine ecological research, as it is subject to the interaction among several natural forcing (river, groundwater discharge, tides, general circulation, intense meteorological) and numerous anthropogenic activities (maritime transport, harbours of Trieste and Monfalcone, urban waste discharge, mussel- and fish-farming, fishing and recreational activities). In 1999, the ecological research site has been equipped with a meteo oceanographic buoy (MAMBO) in order to acquire continuous data on meteorological conditions at sea and on seawater physical and biogeochemical properties. Due to the high temporal dynamics of ecological processes in coastal ecosystems, continuous and real-time data of the main meteorological, physical and biogeochemical properties are fundamental for a better understanding of marine ecosystem functioning.

The HOBE experimental catchment is located in the western part of Denmark. The topography of the catchment is relatively flat. The surface elevations in the eastern part of the catchment are about 125 m above sea level at the Jutland ridge and gently decreasing to sea level elevations towards the coast. Alluvial outwash deposits in the form of sand and gravel dominate the central part of the catchment. Towards east, glacial deposits of moraine till are present with a higher content of clay. Also the remnants from the Saale glaciation have higher clay content and the dominant sediment type at these locations is clayey sand. Overall the top sediments are highly permeable with little water retention capability and the stream flow is therefore dominated by groundwater inflow. Based on a classification of the topsoil four soil classes can be identified in the catchment. The by far most dominating soil type is fine/coarse sandy soil. The Quaternary deposits have a thickness less than 50 m in the eastern and central part of the area increasing up to 250 m towards west. The Quaternary deposits are underlain by Miocene sediments in the form of alternating layers of marine, lacustrine and fluvial deposits forming layers of clay, silt, sand and gravel. Further below thick layers of Paleogene clay are found with little permeability and thus acting as a lower impermeable boundary for the aquifer systems. The sand and gravel layers from the Quaternary and Miocene periods form interconnected aquifer systems. The land surface of the catchment is predominantly agriculture and due to the sandy soil characteristics extensive irrigation of the agricultural crops takes place. Based on satellite data the land-use distribution is estimated as follows: grain and corn (55%), grass (30%), forest (7%), heath (5%), urban (2%) and other (1%). The climate of the observatory is of maritime origin and influenced by weather systems coming from the Atlantic Ocean. The weather conditions are variable with frequent precipitation. The prevailing winds from west lead to relatively mild winters and cool summers. The mean annual precipitation is about 1050 mm/year. It varies over the season with highest amounts in the months of October-December and lowest in the months of April-May. The mean annual temperature is 8.20C. The highest mean monthly temperature is in August (16.50C) and the lowest in January (1.40C). Precipitation in the form of snow is highly variable from year to year; in some years, no snowfall occurs and in others, it may stay on the ground for months.

Historically, the role of the Galapagos Islands has been considered critical due to the evolutionary diversification induced by natural and historical isolation. The Galapagos National Park was established in 1959, based on its historical importance associated with Charles Darwin's voyage and its rare and endemic biodiversity, composed of unique vertebrate and plant communities (Rozzi et al. 2010). In 1978, the Galapagos Islands were declared a UNESCO World Heritage Site, a critical factor associated with this national park (Rozzi et al. 2010). The Galapagos Islands are a pristine area with local and regional climates influenced by the interaction of ocean currents and winds driven by the Inter-Tropical Convergence Zone; ITCZ (Conroy et al. 2008, Trueman and d'Ozouville 2010). The long-term programme includes forty natural aquatic ecosystems (lakes, ponds, lagoons and swamps) that will be sampled on the islands of San Cristobal, Santa Cruz, Isabela and Floreana, where possible along a lowland-highland gradient. The number of sampling points will vary according to environmental heterogeneity and the presence of a littoral region, among other factors.
