title: Ferromanganese nodules and crusts chemical analysis of samples from cruise L583HW (R/V S.P. Lee) using X-ray

description: The cooperative cruise of the R/V S.P. Lee in 1983 provided an excellent opportunity for a wide-range interlaboratory study on samples of crusts ground and sieved aboard the vessel. Analytical data on splits of approximately 56 samples were performed by the U.S. Geological Survey laboratories in Reston Virginia and Woods Hole Massachusetts, (see Chapter V), the Bureau of Mines laboratory in Avondale, Maryland, and the laboratory of the German Geological Survey in Hannover, Federal Republic of Germany. At USGS Woods-Hole, 2.0 cm thick mini-slabs from ferromanganese crust or nodule outer surface were separated into horizons and layers. They were ground and sieved through a 105 micron nylon mesh. Remaining ferromanganese material was removed by washing with 10 percent hydroxylamine hydrochloride (NH2OH.HCL) and 1 percent oxalic acid. Samples were first dried at 110°C overnight for the determination of hydroscopic water (H2O-). Major and minor element concentrations were determined by X-ray fluorescence spectrometry.
description: From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.This dataset represents a part of the digitized Table 4, pp. C04-1 to C04-7 of the related publication.

title: Raw values of boundary layer I2 measurements at Neumayer III station, Antarctica from January 2016 to August 2018

description: From January 2016 until August 2018, an automated Long-Path Differential Optical Absorption Spectroscopy (LP-DOAS) instrument was operated at the German research station Neumayer III (NMIII) in coastal Antarctica to measure trace gas mixing ratios in the boundary layer close to the ground (average altitude above the snow surface: 4m). Two different atmospheric light paths with total lengths of 3100 m and 5900m were used depending on visibility.The DOAS evaluation of I2 was performed between 532.5 and 549 nm. Fits with residual optical density RMS (root mean square) values larger than 4.0e-4 were discarded. The resulting mean residual RMS is 2.3e-4. The mean detection limit is 78 pmol/mol.The data sets include the observations below the respective detection limit scattered around 0, which due to the spectral analysis with the DOAS approach can include negative values. I2 was not detected above a 3-sigma detection limit. Since total errors and hence detection limits are determined from spectral information, the detection limit of I2 can serve as an upper limit for an atmospheric presence.The mixing ratios provided here were calculated using meteorological data from Neumayer III station already published on PANGAEA. A list of data sets is included in the "Related to" section of the bibliography this data set is part of.The spectral raw data of the measurements is stored on the measurement data server of the Institute of Environmental Physics, University of Heidelberg.

title: Eddy Covariance measurements in a semi-arid mangrove ecosystem on the coastal line of Magdalena Bay in the Mexican State of Baja California Sur

description: The objective of this database is to measure and identify the seasonal variation of meteorological conditions and atmospheric carbon flux of a semi-arid mangrove ecosystem on the coastal line of Magdalena Bay in the Mexican State of Baja California Sur. This dataset is part of a larger project entitled Carbon Flux in a Semi-Arid Mangrove Ecosystem in Magdalena Bay, B.C.S Mexico. The project and meteorological station were managed and operated primarily by the first author. Local support was provided by the Centro de Investigaciones Biológicas del Noroeste (CIBNOR) and funded by San Diego State University and NOAA Educational Partnership Program/ Center for Earth System Sciences and Remote Sensing Technologies.------------------The study site is located along the northern extent of Magdalena Bay (Bahia Magdalena), which is about 10 km north of the fishing town of Puerto Adolfo Lopez Mateos, BCS, Mexico (25°15'44N, 112° 4'48W). The area is a contiguous series of productive and biologically diverse embayments, intertidal mud flats, and mangrove-lined canals bounded by islands and sand bars that extend for 175 km along the Pacific coast of BCS. The site is located within the largest of these bays in the northwest region of Magdalena Bay in an area bordered by the sandy barrier island of Isla Magdalena, which forms a protected inner shelf lagoon that connects the inner lagoons and canals to the Pacific Ocean via the "Boca de Soledad". Magdalena Bay is characterized by a high floral and faunal diversity, where the arid desert region transitions into a coastal area. Seasonal upwelling in the sub-tropical California Current allows high rates of productivity in the bay, which is dominated by surf grass, eel grass, intertidal mud flats, salt marshes, and mangrove lined coastlines. The dominant mangroves species found in this area are red (Rhizophora mangle), white (Laguncularia racemosa) and black (Avicennia germinans) mangrove trees.------------------Data was collected for 22 days between January 8 and 30, 2012; for 69 days during summer between June 20 and August 28th, 2012; and for 19 days between January 5 and 24 in 2013. January 2012, and January 2013 were grouped together as winter and the months of June through August were grouped as Summer for seasonal period analysis.The EC system included a fast response (10Hz) three-dimensional sonic anemometer (CSAT3, Campbell Scientific Inc., Logan, UT, USA) used to measure wind velocity and sonic temperature fluctuations. Atmospheric CO2 and water vapor concentrations were measured by a fast response (10Hz) open-path infrared gas analyzer (IRGA) (LI-7500, LI-COR Inc., Lincoln, NE, USA) at 5 m above the ground.
