The expedition PS155/1 started on August 5th, 2018 in Tromsø (Norway) and ended in Longyearbyen (Spitsbergen) on September 3rd, 2018. In the course of BGR’s GREENMATE project the geological development of the European North Atlantic and the northern and north eastern Greenland shelf was analyzed using various marine geophysical methods (seismics, magnetics, gravity, heatflow measurements) and geological sampling (gravity corer, box corer, multi-corer, dredge). Sampling of marine Shelf sediments was undertaken in close correspondence with co-users from Geomar (add-on project ECHONEG), aiming to reconstruct Holocene paleo environmental and climatic evolution. Using the ship’s helicopters, marine sampling was complemented by onshore sampling operations to extract geological material at selected near coastal locations. Other scientific project groups used the cruise PS115.1 as an opportunity to quantify marine mammals and sea birds and their statistical distribution in our research area as part of the long-term project (add-on project Birds& Mammals) and to gather additional meteorological data via radiosondes (add-on Project YOPP). Against all expectations, outstanding ice conditions along the northern coast of Greenland enabled us to carry out reflection seismic surveys north of 84°N at the southern tip of Morris Jesup Rise with a 3 km long streamer. Structural data of this particular region of North Greenland is of special importance for BGR’s project GREENMATE for reconstructing the continental margin evolution. A 100 km long refraction seismic profile was measured to complement the reflection seismic data. After completing this, scientific work was concentrated on the northeastern Greenland shelf area between 76°N and 82.5°N. Over the time of the cruise a total of 2500 km of reflection seismic profiles (2250 km measured with 3km streamer length) and 100 km of refraction seismic profile (using nine ocean bottom seismometers) were measured, accompanied by gravity and magnetic surveys and seven heat flow measurement stations. Along the shelf and deep-sea area 21 geological sampling sites were chosen, with all together one dredge (around 200 kg of sample), 16 gravity cores (total core length 65 m), 12 box corers and 6 multi-corer stations. Onshore sediment sampling was done at 11 sampling sites. Beside sediment sampling hard rock from near coastal outcrops was collected in a total amount of 250 kg that will be used for age dating. The entire science program was carried out under consideration of the highest ecological standards to protect marine mammals and to meet all environmental requirements of the permitting authorities. In addition to external marine mammal observers (MMO) various acoustic monitoring systems and AWI’s on board infrared detection system AIMMS monitored any activity of marine mammals in the ships perimeter, especially during seismic operations.
In the period from February 13th to March 2nd 1980 4,037 km of magnetic, gravity and bathymetric lines and 1,195 km of digital reflection seismic lines were recovered on the 2nd leg of METEOR cruise no. 53. Heat flow measurements have been performed on 13 stations; on two stations sonobuoy refraction measurements and dredging have been carried out. From a preliminary interpretation of the seismic monitor records the Mazagan Plateau is part of the Moroccan Meseta. Seawards of this stable swell lies the 75 km wide, downfaulted rift graben characterized by salt diapirs. A submarine body, 150 square kilometres large, lying at the foot of the Mazagan Escarpment in water depths of 3000 m - 3800 m beneath sea level, from which western flank few granitic fragments were retrieved, is interpreted as a subsided and tilted block of the Mazagan Plateau. The north-trending magnetic anomalies, discovered during METEOR cruise no. 46 within the Essaouira continental margin segment have also been recognized within the Tafelney Plateau segment, situated between latitudes 30°45'N and 31°30'N off Morocco. Two neo-volcanic zones were found west of the Conception Bank and west of the Betancuria Massif/Fuerteventura Is. The Mesozoic and Tertiary depositional sequences are highly deformed by small piercement structures interpreted as dykes within these zones.
The SONNE cruise SO-49/1 from 6th April to 7th May 1987 was designed to investigate the Cotabato subduction zone off Mindanao and the geological structure of the eastern part of the Sulu Sea including the convergent continental margins off Zamboanga Peninsula, Negros, and Panay by a geophysical survey. On the 1st leg multichannel seismic reflection measurements were carried out in parallel with magnetic, gravimetric, sea beam and 3.5 kHz subbottom profiler measurements on 16 lines with a total length of 2,700 km. The SONNE cruise SO-49/1 was financed by the Federal Ministry of Research and Technology (BMFT). The geophysical survey in the Celebes Sea and in the Sulu Sea was carried out as a co-operative project by the Federal Institute for Geosciences and Natural Resources (BGR), the Bureau of Mines and Geoscience (BMG) and the Bureau of Energy Development (BED). 16 German scientists and technicians and 4 Philippine scientists attended SONNE cruise SO-49/1. The seismic lines surveyed across the Cotabato Trench/Celebes Sea and the Sulu Trench/Sulu Sea illustrate the active deformation of the layered sediments of the Celebes Sea and the SE Sulu Basin along the trenches: The seismic data suggest an active development of imbricate thrust sheets at the toe of the accretionary wedges and a simultaneous duplex-kind shortening within the wedges above the downgoing oceanic crust of the Celebes Sea and the SE Sulu Basin. The surface of the downgoing oceanic crust forms a major detachment plane or sole thrust. By these processes mass is added to the accretionary wedges resulting in thickening and growing of the wedges. The sedimentary apron overlaying the wedge is only mildly affected by these processes because the surface of the accretionary wedges forms a roof thrust. The collected geophysical data suggest that the oceanic SE Sulu Basin previously extended northward into Panay Island. It was closed by eastward subduction of oceanic crust beneath the upthrusted/updomed Cagayan Ridge. The Negros Trench, a 4.000 to 5,000 m deep bathymetric depression, is thought to represent the collision suture of the opposed subduction systems. The Cagayan Ridge which divides the Sulu Sea into the NW Sulu Basin and the SE Sulu Basin continues into the Antique Ridge of Panay. Approximately 45 suitable and problem-oriented sampling locations have been defined and documented for the subsequent geological and geochemical program by on-board analysis and interpretation of the seismic near trace records and the recordings of the 3.5 kHz subbottom profiler and the sea beam system. On cruise SO49/2 from 10th May to 21st June 1987, the research vessel SONNE of the Federal Republic of Germany undertook geoscience cruises in the South China Sea. The multidisciplinary study of the tectonic and natural resources of the region was a cooperative project between the Federal Institute for Geosciences and Natural Resources (BGR) and the Second Institute of Oceanography (SIO) in the frame of the Agreement between the State Oceanic Administration of the People's Republic of China and the Federal Ministry for Research and Technology of the Federal Republic of Germany on Cooperation in Marine Science and Technology. The first part of cruise SO49/2 was primarily to acquire multichannel seismic data, together with gravity, magnetic, sea beam, and 3.5 kHz measurements, and consisted of 4,112 km of traverses across the deep eastern and western sub-basins of the South China Sea from the Dangerous Grounds to the Chinese continental margin. The observed complex crustal deformation in the Southwestern South China Sea basin and in particular deep intracrustal reflection suggest a large-scale simple-shear kinematic mechanism for the development of at least the western sub-basins. The second part of cruise SO49/2 had primarily geological, geochemical and geothermal objectives and 21 dredge stations, 17 geochemical stations and 6 heat flow stations were carried out. The aims of the sampling were firstly to determine the lithologies and ages of the seismic sequences, and secondly to collect unconsolidated sediments for geochemical study of sorbed hydrocarbon gases in combination with heat flow measurements. Late Oligocene shallow-water carbonates dredged from 700 m to 2700 m of water depth indicate a strong subsidence of the investigated area. The underlying basement consists of continental crust with basaltic intrusions. The hydrocarbon gases of the outer continental slope originated by thermogenic processes from source rocks with a predominantly high maturity of the organic substances.

Two irrigated apple orchards, S09 and S10, within the Pinios Hydrologic Observatory in Thessaly, Greece were equipped with an extensive sensor network to study irrigation management. Soil moisture dynamics (including soil matric potential), irrigation water consumption, meteorological variables and sap flow were monitored between September 2020 and Dec 2022. In each field, an Atmos41 all-in-one weather station (Meter Group AG, Munich, Germany) was installed close to the centre of the field above the tree canopy. The instruments provided measurements of precipitation, air temperature, relative humidity, solar radiation, wind speed, and atmospheric pressure. Furthermore, each field was equipped with a SoilNet wireless sensor network consisting of 12 nodes. Each node was equipped with six SMT100 (Truebner GmbH, Neustadt, Germany) installed at 5, 20, and 50 cm depth, in two separate profiles to measure soil moisture as well as two TEROS21 soil matric potential sensors (METER Group Inc., Pullman, USA) installed at 20 cm depth. Additionally, S10 was equipped with six SFM-1 sapflow sensors (ICT International Pty Ltd, Armidale, Australia) to estimate whole-tree transpiration. The sapflow sensors were installed on the trunk of six trees to represent, as much as possible, the orchard trees in terms of height, perimeter, vigor and apple variety. Lastly, in May 2021 seven TW-N flowmeters (TECNIDRO, Genova, Italy) were installed in different irrigation sectors within the orchards (three in S09 and four in S10) to measure field-scale irrigation water consumption. All data is provided at a daily timescale.
TERENO Eifel-Rur Observatory. TERENO (TERrestrial ENvironmental Observatories) spans an Earth observation network across Germany that extends from the North German lowlands to the Bavarian Alps. This unique large-scale project aims to catalogue the longterm ecological, social and economic impact of global change at regional level. The central monitoring site of the TERENO Eifel/Lower Rhine Valley Observatory is the catchment area of the River Rur. It covers a total area of 2354 km² and exhibits a distinct land use gradient: The lowland region in the northern part is characterised by urbanisation and intensive agriculture whereas the low mountain range in the southern part is sparsely populated and includes several drinking water reservoirs. Furthermore, the Eifel National Park is situated in the southern part of the Rur catchment serving as a reference site. Intensive test sites are placed along a transect across the Rur catchments in representative land cover, soil, and geologic settings. The Rollesbroich site is located in the low mountain range “Eifel” near the German-Belgium border and covers the area of the small Kieselbach catchment (40 ha) with altitudes ranging from 474 to 518 m.a.s.l.. The climate is temperate maritime with a mean annual air temperature and precipitation of 7.7 °C and 1033 mm, respectively, for the period from 1981 to 2001. The study site is highly instrumented. All components of the water balance (e.g. precipitation, evapotranspiration, runoff, soil water content) are continuously monitored using state-of-the-art instrumentation, including weighable lysimeters, runoff gauges, cosmic-ray soil moisture sensors, a wireless sensor network that monitors soil temperature, and soil moisture at 189 locations in different depths (5, 20 and 50 cm) throughout the study site. Periodically also different chamber measurements were made to access soil or plant gas exchange. Runoff is measured at the catchment outlet using a gauging station equipped with a combination of a V-notch weir for low flow measurements and a Parshall flume to measure normal to high flows. Runoff data of the two weir types are combined by using V-notch values for water levels below 5 cm, Parshall flume values for water levels greater than 10 cm and the weighted mean of V-notch and Parshall flume values for water levels between 5 and 10 cm, where the water levels refer to those of the V-notch weir. Meteorological data, i.e. precipitation, air temperature, air humidity, radiation components, and wind speed, were recorded at 2 m height next to the runoff gauging station As a first quality check, time series of both gauge types were compared for consistency. In addition, both runoff time series were visually inspected for inexplicable outliers (e.g. runoff peak without preceding rainfall event) and sensor failures. Unreliable data were identified by visual inspection and appropriate flags were set.
