title: Trans Isthmus Costa Rica Scientific Exploration of a Crustal Transect - seismic refraction data from profiles p301 and p302 of Maurice Ewing cruise EW9502 with links to sgy data files

description: The TICOSECT program aimed to investigate the crustal structure of the active continental margin of Costa Rica and to understand the geodynamic processes within the subduction system. With the help of a comprehensive wide-angle seismic data set, composed of an onshore/offshore experiment as well as refraction measurements on land in northern Costa Rica, the lithospheric structure from the Middle America Trench (MAT) to the Caribbean lowland was surveyed seismically.Here we provide seismic refraction data from an onshore/offshore seismic profile shot with the US American research vessel RV Mauris Ewing in spring of 1995 offshore of the Osa peninsula during the cruise EW9502. Data are reduced with 6 km/s and origin of the time series is at -2 sec. Note: the profile has been shot twice with a different shot interval at 25 s (p301) and 60 s (p302). Additional data from US partners can be found at http://www-udc.ig.utexas.edu/sdc/cruise.php?cruiseIn=ew9502.

title: Compositions of experimental major elements in the mantle transition zone

description: The starting materials are two carbonated basalt compositions with CO2 concentrations of 2.5 wt% (PC-a) and 5.0 wt% (PC-b), respectively. The partial melting experimental were conducted at the Laboratory for the Study of the Earth's Deep Interior (SEDI-Lab), China University of Geosciences (Wuhan), using 10/5 and 18/12 cell assemblages combined with a 1000-ton Walker-type multi-anvil press. The experimental pressure and temperature conditions are 13-20 GPa and 1300-1600 oC, respectively. Five phases were observed in the run products: garnet, clinopyroxene, stishovite, magnesite, and quench melt. The chemical compositions of phases were examined by an electron probe micro-analyzer (EPMA, JXA-8100) at the Key Laboratory of Submarine Geosciences, State Oceanic Administration. The accelerating voltage, beam size, and beam current were 15 kV, 5.0–10.0 μm and 10 nA, respectively. Count times were 10s for each of the measured element and 5s for the background. Standard materials were diopside for Si, rutile for Ti, pyrope for Al, Cr2O3 for Cr, CaSiO3 for Ca, Mg2SiO4 for Mg, Fe2O3 for Fe, MnSiO3 for Mn, NiO for Ni, jadeite for Na, K-feldspar for K, and Ca5P3F for P. The relative uncertainties were ~5% for elements of less than 1 wt%, ~1% for elements of ~1–5 wt%, and less than 0.5% for elements of greater than 5 wt%.

title: High-resolution surface global solar radiation and the diffuse component dataset over China (2013)

description: Surface solar radiation drives the water cycle and energy exchange on the earth's surface, and its diffuse component can promote carbon uptake in ecosystems by increasing the plant productivity. The accurate knowledge of their spatial distribution is of great importance to many studies and applications, such as the estimation of agricultural yield, carbon dynamics of terrestrial systems, site selection of solar power plants, as well as trends of regional climate changes. Therefore, we produce the hourly surface radiation datasets based on the hourly Multi-functional Transport Satellite (MTSAT) satellite imagery and the ground observations from the China Meteorology Administration (CMA) through deep learning techniques. The deep network is trained using training samples in 2008, and then utilized to generate the hourly radiation for other years. This dataset provides the gridded surface global and diffuse solar radiation in 2013 within 71.025°E - 141.025°E and 14.975°N - 59.975°N with an increment of 0.05°. Both the direct predicted hourly values and the integrated daily and monthly total values are available. The dataset should be useful for the analysis of the regional differences and temporal cycles of solar radiation in fine scales, and the impact of diffuse radiation on plant growth etc.

title: Tongan socio-environmental spatial layers for marine ecosystem management

description: Environmental conditions and anthropogenic impacts are key influences on ecological processes and associated ecosystem services. Effective management of Tonga's marine ecosystems therefore depends on accurate and up-to-date knowledge of environmental and anthropogenic variables. Although many types of environmental and anthropogenic data are now available in global layers, they are often inaccessible to end users, particularly in developing countries with limited accessibility and analytical training. Furthermore, the resolution of many global layers might not be sufficient to make informed local decisions. While the near-shore marine ecosystem of Tonga is extensive, the resources available for its management are limited and little is known about its current ecological state. Here we provide a marine socio-environmental dataset covering Tonga's near-shore marine ecosystem as compiled from various global layers, remote sensing projects, local ministries, and the 2016 national census. The dataset consists of eleven environmental and six anthropogenic variables summarized in ecologically relevant ways, spatially overlaid across the near-shore marine ecosystem of Tonga. The environmental variables selected include: bathymetry, coral reef density, distance from deep water, distance from land, distance from major terrestrial inputs, habitat, land area, net primary productivity, salinity, sea surface temperature, and wave energy. The anthropogenic variables selected include: fishing pressure, management status, distance to fish markets, distance from villages, population pressure, and a socioeconomic development index based on population density, growth, mean age, mean education level, and unemployment. This extensive and accessible dataset will be an essential tool for future assessment and management of marine ecosystems in Tonga.

title: Ichthyoplankton composition form CONVERSUT cruise 2, Southern Brazilian Shelf, in 1978

description: The Convergência Subtropical (CONVERSUT) cruise series was conducted by the Departamento de Hidrografia e Navegação (DHN) from the Brazilian Navy on board the Oceanographic Ship (NOc.) Almirante Saldanha. The project objective was to determine the western boundary of the South Atlantic Subtropical Convergence in different times of the year (Hubold, 1980a, 1980b, Cordeiro & Montu, 1991). The first cruise of the series (CONVERSUT_1) was carried out between August and November 1977, between Ilha do Mel (25°S) and Mar del Plata (Argentina, 40°S), resulting in 24 transects perpendicular to the coast and 200 oceanographic stations spaced about 30 nautical miles (~ 55 km) apart. Sampling ranged from the coastal region to the oceanic region, approximately 300 nautical miles away from the coast (Hubold, 1980a). Samples from the second cruise (CONVERSUT_2) were conducted between southern Santa Catarina Island (28°S) and southern region of Mar del Plata (Argentina, 48°30'S) from April to June 1978. Twenty-one transects were performed resulting in 180 oceanographic stations, covering an area that stretched up to 250 nautical miles (463 km) toward the ocean (Hubold, 1980b). The 153 stations on the third cruise of the series (CONVERSUT_3) were the result of 24 transects between Ilha do Mel (25°S) and Mar del Plata (Argentina, 40°S) during the period between January and April 1981 (Cordeiro & Montu, 1991). Two sampling strategies were employed in the first two cruises, oblique and vertical trawls at each station, while in the third cruise only oblique trawls were performed. A conical plankton net (Hensen type) with 0.80 m of mouth diameter, 2.6 m of total length and 250 µm of mesh was used (Hubold, 1980a; Cordeiro & Montu, 1991). For technical reasons, in the second cruise, a Hensen-type network with 0.60 m diameter was used in the oblique trawls (Hubold, 1980b; Hubold, 1982). The oblique and vertical trawls were driven from 200 m depth to the surface, or from within 1-5 m from the bottom in shallow areas. The average velocity during the descent of the net in oblique trawls was 0.5 ms-1, reaching 2 ms-1 on the rise, while in vertical trawls velocity was 1 ms-1 (Hubold, 1982). Flowmeters were coupled in all nets to determine the volume of filtered water in each trawl. Samples were fixed and preserved in buffered formaldehyde solution diluted in sea water with a final approximate concentration of 4% (Hubold & Ehrlich, 1981). The filtered volume was calculated and used to standardize the abundance of fish eggs and larvae per 100 m3 of filtered water.

title: Collection of Sentinel-1 OCN Level 2 RVL products from October and and November 2017 processed for the Fruholmen experiment

description: The dataset contains Sentinel-1 IW Ocean(OCN) Level 2 Radial Velocity (RVL) products acquired over the Norwegian coastal zone in October and November 2017. The processing procedure included the generation of internal Level 1 Single Look Complex (SLC) products using an in-house TOPS mode data processor. The SLC products were then processed using a prototype version of the Sentinel-1 Level 2 processor to get RVL products. The spatial resolution of the final products was about 1.5x1.5 km across a swath of 250 km at incidence angles in the range from 29.1 to 43.1 degrees. Every scene from the dataset was then recalibrated using information acquired over the land. The data are processed in the NORCE Norwegian research center AS.

title: Muted multidecadal climate variability in central Europe during cold stadial periods

description: Here, we present a near-annual-resolution climate proxy record of central European temperature reconstructed from the Eifel maar lakes of Holzmaar and Auel in Germany spanning the past 60,000 years. The lake sediments reveal a series of previously undocumented multidecadal climate cycles of around 20- to 150-years that persisted through the last glacial cycle. The periodicity of these cycles suggests that they are related to the Atlantic multidecadal climate oscillations found in the instrumental record and in other climate archives during the Holocene. Our record shows that multidecadal variability in central Europe was strong during all warm interstadials, but was substantially muted during all cold stadial periods. We suggest that this decrease in multidecadal variability was the result of the atmospheric circulation changes associated with the weakening of the AMOC and the expansion of North Atlantic sea ice cover during the coldest parts of the last ice age.Organic carbon was determined by measuring the reflectance for each wavelength of the visible light as percent relative to a white color standard. Absorption forms a pronounced minimum in the wavelength range of 640 nm – 730 nm in cores both from Holzmaar and Auel. Reflectivity in this wavelength band (I-Band, 660 – 670 nm, i.e. the red part of the spectrum), was shown to relate to sediment concentrations of chlorophyll a and its degradation products.The absorption at 670 nm was calibrated in the first study versus organic carbon and chlorine content, both of which revealed a significant relation to the “In situ Reflectance Spectroscopy – ISRS” absorption at 670 nm, which is subtracted from the interpolated value between 640 and 730 nm. The ISRS670 detects accordingly chlorophyll a, b, and c and also Bacteriochlorophyll c and d (Green sulfur bacteria) as well as their derivates and can be applied to detect trends in total aquatic paleoproduction in both ocean and lake sediments.

title: Mercury Benefits of Climate Policy in China: Addressing the Paris Agreement and Minamata Convention Simultaneously

description: National commitments under the Paris Agreement on climate change interact with other global environmental objectives, such as those of the Minamata Convention on Mercury. We assess how mercury emissions and deposition reductions from national climate policy in China under the Paris Agreement could contribute to the country's commitments under the Minamata Convention. We examine emissions under climate policy scenarios developed using a computable general equilibrium model of China's economy, end-of-pipe control scenarios that meet China's commitments under the Minamata Convention, and these policies in combination, and evaluate deposition using a global atmospheric transport model. We find climate policy in China can provide mercury benefits when implemented with Minamata policy, achieving in the year 2030 approximately 5\% additional reduction in mercury emissions and deposition in China when climate policy achieves a 5% reduction per year in carbon intensity (CO2 emissions 9.7 Gt in 2030). This corresponds to 63 Mg additional mercury emissions reductions in 2030 when implemented with Minamata Convention policy, compared to Minamata policy implemented alone. Climate policy provides emissions reductions in sectors not considered under the Minamata Convention, such as residential combustion. This changes the combination of sectors that contribute to emissions reductions.This data submission includes scripts to project China's 2012 mercury emissions from the Emissions Database for Global Atmospheric Research (EDGAR) and prepare them for input to the global chemical transport model, GEOS-Chem. It also includes scripts to plot projected emissions and plot deposition results (with required raw results from GEOS-Chem) for the figures included in the Environmental Science and Technology article.

title: Increased extreme precipitation in Chinese deserts from 1960 to 2018

description: Extreme precipitation over drylands, especially deserts, has been often observed. The precipitation changes in Chinese deserts have been rarely studied. Here, we use a daily grid precipitation dataset generated via weather station data (0.25° horizontal grid spacing) to investigate the spatial and temporal changes in extreme precipitation in Chinese deserts. The extreme precipitation based on the changes in the total precipitation (PRCPTOT) and the annual-maximum daily precipitation (Rx1day) in the Chinese desert exhibits markedly increasing trends and presents a spatial distribution of wetting in the western deserts and drying in the eastern deserts. The increase in extreme precipitation could minimize wind erosion and intensify dune stabilization in the western Chinese deserts.

title: Spiekeroog beach subterranean estuary & seawater: Dissolved organic matter (DOM) fingerprints

description: Data from pore water (subterranean estuary) and seawater from Spiekeroog south (near ICBM time series station and campsite) and west beach ("Sturmeck"). South beach data were collected in August 2012, and west beach data were collected in November 2012. Pore water (event labels: DUNE, MIX, LTWL) sample collection was conducted at different sediment depths (50, 100, 150 cm below sediment surface). Stainless steel push-point lancets were insetred into the sediment, and pore water was withdrawn via vacuum (hand pumps) into nalgene polycarbonate bottles. Filtration was done using inline PES cartridge filters. The vacuum bottles were argon gas-flushed to avoid oxygen contamination. Sea water (event label SW) was collected with polycarbonate bottles and from LDPE seepage meter bags (event label SP) and filtered upon return to the laboratory (same day, PES filter cartridges). Sample collection was trace organic and metal clean (soaking and rinsing of bottles, tubing, and filters with diluted HNO3 and HCl suprapur), with sample materials consisting of polyethylene, polypropylene, and polycarbonate. Solid-phase extraction was done with BOND Elut PPL cartridges and elution with Methanol Optima grade. Measurements dissolved organic matter (DOM) were done with FT-ICR-MS. The crosstables describe the molecular composition of DOM and associated Fe and Cu. They contain characteristic properties and classifications of molecular sum formulas as well as FT-ICR-MS signal intensities of each sum formula for each sample (see event table of https://doi.pangaea.de/10.1594/PANGAEA.902704).
