title: Chemical composition of sediments from GH80-1 cruise

description: The moisture content and the minor element contents were determined for 115 sediment samples collected from the G H 80-1 survey traverses of the Central Pacific Wake-Tahiti Transect. The minor elements determined were Mn, Fe, Co, Ni, Cu, Zn, and Pb. The data for evaluating the distribution of these components in the ocean floor of the Central Pacific Basin and its northern and southern vicinities were obtained. These sediment samples comprises 24 surface sediment samples and 91 segments from core samples ranging in depth to several meters below the sea bottom. Principal characteristics of the concentration and horizontal distribution of each component in the gross sediment samples are described in this chapter, as well as the relations among the elements. The selected samples were ground under the size of 150 mesh. Moisture content (H2O-) was determined by drying for 3 hours at 110°C. After dissolution of the salts by an acid solution the minor elements (Mn, Fe, Co, Ni, Cu. Zn, and Pb) were determined by the atomic absorption spectroscopy.

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 the digitized Appendix XV-1, pp. 318-337, of the related publication.

title: Chemical composition of manganese nodules from GH80-1 cruise

description: Manganiferous materials were collected at 49 stations in the Central Pacific Basin, the Mid-Pacific Mountains, the Manihiki Plateau, and the Penrhyn Basin during cruise GH80-1. Manganese nodules were selected from 40 stations for analysis. Samples were separately taken from those samplers. During sample preparation materials other than ferromanganese oxide shells such as rock nuclei were visually removed off when possible. Two subsamples were taken when a nodule has a distinct double-layered internal structure. The samples were kept in plastic containers on board for shore-based analyses and were dried in air at room temperature in a few months after the cruise. One hundred and twelve ground samples were prepared for atomic absorption spectroscopic analyses of Mn, Fe, Cu, Ni, Co, Pb, and Zn. The analyses were carried out on the air-dried powdered samples. Total water contents (H2O tot) were measured by gravimetric method also on the air-dried powdered samples. Acid insoluble fractions were not determined, though these fractions occasionally amount several tens of per cent of nodules.

title: Major and trace element abundance in sediment samples from ODP Hole 121-758B (Table 1)

description: Major and trace element analyses of 30 sediment samples from ODP Core 758B across the Brunhes-Matuyama geomagnetic polarity reversal and the Australasian microtektite-bearing layer show a small but significant anomaly in the elemental abundances of Ir, Co and Ni. The maximum of the anomaly between 10.89 and 11.00 m below seafloor correlates with the maximum abundance of microtektites. Iridium abundances, which show the most significant anomaly, reach 0.16 ppb, which is evidence for an extraterrestrial component.

title: Beach profile data for the Elwha River Delta, 2011-04-08

description: Data were collected using GNSS survey methods, with a differential GPS operating in Real Time Kinematic (RTK) mode. Data from prior to 2013 were typically collected with a Magellan ProMark 3 traditional RKT-DGPS system (i.e. local base station and rover), with the base station sited on survey control markers installed in 1996, with survey control coordinates referenced to NAD83(CORS91). Starting in 2013 survey data were typically collected with an AshTech ProMark 200 RTK-DGPS system connected to the Washington State Reference Network. Survey data collected between January and November 2013 are referenced to NAD83(CORS96), and after November 2013 to NAD83(2011). Vertical data for surveys in 2012 and 2013 are referenced to NAVD88, presumably using Geoid96 (the survey control documentation does not specific a geoid). For all subsequent surveys the vertical data are referenced to NAVD88(Geoid09). No conversion were applied to these data to account for variations in horizontal or vertical coordinate system adjustments through time, but an error analysis suggests a standard deviation for the elevation data of between 0.03 and 0.05 m across the entire sampling period (2011-2018). All survey data were collected with the GNSS system mounted on a 2.05 m rover pole, held level as a transect line was traced in a cross-shore orientation on the beach. The associated text files include the horizontal (HRMS) and vertical (VRMS) root-mean-square errors estimated by the GNSS system, as well as the RTK-DGPS status reported by the GNSS system at the time each point was collected. Times are referenced to local Pacific time (either PST or PDT).

title: Primary production of organic carbon in the Atlantic Ocean

description: Relatively high production (100-1000 mgC/m**2 per day) was noted in the Canary current area, with maximum values in the region located between Dakar and the Cape Verde Islands. Rather low production (up to 100 mgC/m**2) was noted in central sectors of the Gulf of Guinea and in middle regions of the southeastern anticyclonic gyre. The most heterogeneous production was noted in neritic areas of the southwestern African coast, where production varied from 43 to 17873 mgC/m**2 per day, whereby the most intensive photosynthesis was clearly confined to near-estuary areas of the Ogova (1588), Congo (695), Cuene (2771) and Orange (17873 mgC/m**2 per day) rivers. Diurnal rhythm of production exhibited sharp increase in production in series of samples taken during evening hours and similarly sharp decrease in production in samples taken at night or before dawn.

title: 40Ar/39Ar age constraints to MIS 5.5 and MIS 5.3 paleo-sea levels: implications for global sea levels and ice-volume estimation

description: We present ten 40Ar/39Ar age determinations, both on primary volcanic deposits and on detrital sanidine, which provide geochronologic control on the MIS 5.5 and MIS 5.3 sea-level indicators that occur at three coastal caves in the central Tyrrhenian Sea of Italy.Samples dated for the present work are as follows:- Two pumice clasts (MOSC-22, MOSC-37) extracted from the sand layers constituting the sedimentary fill of Moscerini Cave, recovered during the original archaeological excavations performed in the year 1949, stored at the IIPU (Istituto Italiano di Paleontolgia Umana) repository in Anagni (Frosinone, italy).These two samples were processed at the rare Gas Laboratory of the University of Wisconsin Madison in March, 2019.- One tephra layer (sample GDC-10) intercalated in the sedimentary fill of Capre Cave collected in June, 2021.- Seven sedimentary sand samples collected at Guattari Cave (GU-1, GU-5, GU-105, GU-116) in June, 2020, and at Capre Cave (GDC-6, GDC-8, GDC-0) in June, 2021 .These dates constrain the age of a Strombus-bearing biodetritic conglomerate associated with a tidal notch occurring at 9.5 m a.s.l. at Cape Circeo between 121.5±5.8 and 116.2±1.2 ka. Moreover, deposition of backbeach deposits intercalated in the sedimentary filling of Guattari and Capre coastal caves is bracketed in the interval 110.4±1.4 ka to 104.9±0.9 ka. Such deposits are directly correlated with a tidal notch at ~2.5 m associated with another biodetritic conglomerate at Cape Circeo. The latter is correlated with the adjacent marine terrace, occurring at 3-5 m in the coast between Capes Circeo and Anzio, for which a maximum age of 100.7±6.6 ka was previously reported. These data provide evidence for a maximum sea level around 9.5 m above the present sea level and a duration of MIS 5.5 highstand until 116 ka, in line with estimation from other regions in the world. In contrast, they suggest a maximum sea level during MIS 5.3 highstand that is similar to the present level, and only ~7 m lower than the MIS 5.5 highstand, challenging the reconstructions of the MIS 5 ice-sheet volumes and derived global sea levels that are based on the benthic oxygen isotope records.

title: Detecting level of wetland encroachment for urban agriculture in Uganda using hyper-temporal remote sensing - classifiedlandstat2016

description: Background: Urbanization is an important indicator of economic growth and social change but is associated with environmental degradation, which threatens sustainable growth of African cities. One of the most vulnerable ecosystems in urban areas are wetlands. In Uganda, wetlands cover an area of 11% of the country's land area. Half of the wetland areas in Ugandan cities have been converted to industry and residential areas, and urban agriculture. There is limited information on the extent of wetland conversion or utilization for urban agriculture. The objective of this study was to investigate the extent of wetlands lost in two Ugandan cities, Wakiso and Kampala, in the last 30 years. Secondly, we demonstrate a simple methodology to monitor agriculture on encroached wetlands.Methods: Using a field survey and free remote sensing data from Landsat TM 1986 and Landsat ETM 2016 we classified the rate of wetland loss and encroachment in the last 30 years. Using MODIS NDVI 16-day composites at 500-meter spatial resolution, we generated distinctive crops and crop mixtures in the encroached wetlands for urban agriculture using the ISODATA clustering algorithm.Results: Over a 30-year period, 72,828 ha (73%) of the Wakiso-Kampala wetlands have been lost. Agriculture area on the other hand doubled. Of the new cultivation area, 16,488 ha (23%) were reclaimed from wetlands. All cultivated agriculture in Kampala was in the wetlands while in Wakiso, 73% of crop agriculture was in the wetlands. The major crops grown in these urban wetlands were banana (20%), sugarcane (22%), maize (17%), Eucalyptus trees (12%), sweet potatoes (10%), while ornamental nurseries, pine trees, vegetables and passion fruits were each at 5%.Conclusions: Current wetland exploitation for food security for urban dwellers may be a trade-off between the provision of food in the short-term and the loss of important ecosystems services in the long-term.
