title: (Table 1) Interstitial water chemistry at DSDP Leg 59 Holes

description: Interstitial water studies of samples from Leg 59 show small concentration variations from sea water in Sites 447 and 451 but very large concentration changes in Site 450. A general analysis of calcium concentration gradients in this region is presented, which emphasizes the anomaly presented by the interstitial water chemistry of Sites 53 and 450 in the Parece Vela Basin. An analysis of concentration changes in Ca, Mg, Sr, Li, Mn, and Si indicates that reaction zones associated with high concentrations of dissolved silica can account for these observations.

title: Annotated record of the detailed examination of Mn deposits from the Snellius II - Cruise 4 stations in the vicinity of the island of Misool, Eastern Indonesia

description: The chemical analyses of ferromanganese encrustations found on the seabed west of Misool, eastern Indonesia, indicate that these deposits formed in a way different from that of world-wide occurring manganese nodules. Ferromanganese coated pebbles and fragments that were found in the deeper parts of the study area probably originate from nearby ridges. The ferromanganese crust on the upper part of a dolomite fragment of ?30 kg is likely to be formed by hydrogenous processes, whereas that from the lower part seems to be formed by diagenetic processes mainly. These assumptions are supported by pore-water data from two box cores taken in the same area. The manganese and iron profiles versus depth in these cores indicate a high flux of these metals to the uppermost sediment layer, and possibly into the overlying bottom water. Factor analysis for the principal components of the microprobe analytical results of the mainly hydrogenous ferromanganese crust demonstrates a strong correlation of manganese with the trace metals, of iron with phosphorus and an antipathetic relationship between iron and manganese. Similar results have also been reported for abyssal manganese nodules in the world oceans. Factor analysis for the principal components of the analytical data obtained for the diagenetic ferromanganese crust results in a clear dolomite (Ca/Mg) dilution factor only.

title: Observation of manganese nodules recovered by the USCGS Oceanographer in 1968 over the Blanco Fracture zone, Pacific Ocean

description: Preliminary results of a 14-day cruise of the USC&GS ship Oceanographer to the area near the junction of Juan de Fuca Ridge and the Blanco Fracture Zone are reported. About 10 full days of bathymetry (using a narrow beam transducer), magnetic, and gravity were completed. Fifteen dredges were attempted, 13 were successful. A striking bathymetric symmetry up to 15 miles on each side of the axis was found on five crossings of the Juan de Fuca Ridge. This symmetry extends at least 17 and possibly 30 nautical miles along the Ridge axis. Relief features, ranging from 100 to 20 fathoms, were found to correlate with similar features across the axis. This bathymetric symmetry is more striking than the magnetic symmetry and is an independent line of evidence in support of sea-floor spreading. A small, median perched graben along portions of the Juan de Fuca Ridge axis is floored by a very recent basaltic flows which have unusual surface structures.

title: Annotated record of the detailed examination of ferromanganese crusts from the Galapagos Ridge area

description: Volcanic rocks, dredged from depths greater than 1000 m on the Galapagos spreading center, show extreme chemical diversity, including rhyodacites, andesite, ferro-basalts, and low-K oceanic tholeiite. All samples have fresh glassy margins. The ferro-basalts contain up to 18.5% total iron as FeO and up to 3.75% TiO2, while the oceanic tholeiites are as low as 0.02% K2O. The ferro-basalts correlate with the previously proposed zone of high magnetic anomaly amplitudes which flank the Galapagos hot spot, and are consistent with a genesis by shallow fractional crystallization.

title: delta Deuterium of alkenone and BIT index of sediment core 64PE304-80 samples

description: Reconstructing past ocean salinity is important for assessing paleoceanographic change and therefore past climatic dynamics. Commonly, sea water salinity reconstruction is based on foraminifera oxygen isotope ratio values combined with sea surface temperature reconstruction. However, the approach relies on multiple proxies, resulting in relatively large uncertainty and, consequently, relatively low accuracy of salinity estimates. An alternative tool for past ocean salinity reconstruction is the hydrogen isotope composition of long chain (C37) alkenones (dDalkenone). Here, we applied dDalkenone to a 39 ka long coastal sediment record from the Eastern South African continental shelf in the Mozambique Channel, close to the Zambezi River mouth. Despite changes in global sea water dD related to glacial - interglacial ice volume effects, no clear changes were observed in the dDalkenone record throughout the entire 39 ka. The BIT index record from the same core showed high BIT values during the glacial and low values during the Holocene. This indicates a more pronounced freshwater influence at the core location during the glacial, resulting in alkenones depleted in deuterium during that time and, thereby, explains the lack of a clear glacial-interglacial alkenone dD shift. Correlation between the BIT index and dDalkenone during the glacial period suggests that increased continental runoff potentially changed the growth conditions of the alkenone producing haptophytes, promoting coastal haptophyte species with generally more enriched dDalkenone values. We therefore suggest that the application of dDalkenone for reconstructing past salinity in coastal settings may be complicated by changes in the alkenone producing haptophyte community.

title: SPM in situ data at Patos Lagoon estuary in 4 stations: Feitoria, Marambaia, Praticagem, and Porto Rei - Fernandes (1998)

description: Fernandes (Fernandes, E. H.: Modelling the Hydrodynamics of the Patos Lagoon, Brazil, Ph.D. thesis, University of Plymouth, 2001) aimed to calibrate the hydrodynamic model TELEMAC for the Patos Lagoon for the first time. The author executed SPM field measurements at 4 stations: Feitoria, Marambaia, and Praticagem (between 27-29 October, 1998), and at Porto Rei (between 05-06 November, 1998) and measurements were carried out at the surface, middle depth and bottom using horizontal bottle samplers. These consist of a simple PVC pipe closed at the ends by rubber stoppers and released by a messenger sent from the surface. Sub-samples were stored in plastic bottles for further filtration and determination of SPM content. Samples were filtered through CA filters of 45 μm pore size as in Baumgarten et al. (Baumgarten, M., Rocha, J., and Niencheski, L.: Manual de Análises em Oceanografia Química, FURG, Rio Grande, Brazil, 1996).

title: Non-destructive particle analyses from different surface sediment samples of Lake Towuti, Indonesia

description: At the University of Cologne, Germany, a subsample was taken from one aliquot and used to produce smear slides for identification of sedimentary components using transmitted light microscopy. On selected samples, sponge spicules and diatom frustules were additionally investigated using a Zeiss Gemini Sigma 300VP scanning electron microscope (SEM; Carl Zeiss AG, Oberkochen, Germany). Furthermore, some magnetic mineral grains were identified with energy dispersive X-ray spectroscopy (EDX) of the Sigma SEM system.Based on smear slide analyses, a set of 40 samples that contain sponge spicules, diatoms and/or tephra particles were selected for automated, non-destructive particle image analyses using a dynamic imaging system (Benchtop B3 Series VS FlowCAM®; Fluid Imaging Technologies, Inc., Scarborough, ME, USA) to quantify the abundance of these particles. Aliquots of wet bulk samples were treated with hydrogen peroxide (H2O2; 30%) for seven days at room temperature to remove organic matter (OM) and disaggregate the siliceous biogenic particles, and were subsequently sieved with 25 and 80 µm meshes. The pre-treated sample fractions were diluted with deionized water (samples &lt;25 µm) or polyvinyl pyrrolidone (PVP, 2 %; samples 25 to 80 µm and &gt;80 µm). Particle recording in the &lt;25 µm and 25 to 80 µm fractions was carried out using a 100 µm flowcell, a 10x objective lens with a collimator, and a 1 ml syringe-pump (flow rate 0.3 ml/min), whereas the &gt;80 µm fraction was recorded using a 300 µm flowcell, a 4x objective lens without collimator, and a 5 ml syringe-pump (flow rate 0.6 ml/min). Data were acquired using the software VisualSpreadsheet (Fluid Imaging Technologies, Inc., Scarborough, ME, USA) until 10.000 images were recorded or 30 ml of the sample was investigated. An automated catalogue based on training sets developed for sponge spicules, diatoms and tephra particles was compiled to differentiate and group components with comparable characteristics in the measured sample fractions.

title: The rating-curve approach derived SPM in Guaíba River and Camaquã River from monthly river discharge data - Jung (1988 - 1990)

description: Jung (Jung, B. M.: Variabilidade dos Fluxos de Sedimentos em Suspensão para a Lagoa dos Patos e os Processos de Trocas com o OceanoAdjacente, Master's thesis, Universidade Federal do Rio Grande - FURG, Rio Grande, Brazil, 2017) used the suspended sediment rating-curve approach to derive SPM concentrations from riverine outflow at the Guaíba River (from 1988 to 1990), Camaquã River (1988-1990), and São Gonçalo Channel (2009-2014). The method assumes a uniform flow in the water column therefore SPM estimates are considered uniform from surface to bottom. The author's work used monthly averaged SPM field data from 'Agência Nacional de Águas' (ANA; http://www.snirh.gov.br/hidroweb), Baisch (Baisch, P.: Les Oligo-Elements Metallique du Systeme Fluvio-Lagunare dos Patos (Bresil) - Flux et deverir, Ph.D. thesis, L'Université Bordeaux I, 1994) and Avila (Avila, R. A.: Distribuição do material particulado em suspensão e suas inter-relações com diferentes propriedades no estuário da Lagoa dosPatos, Master's thesis, Universidade Federal do Rio Grande - FURG, Rio Grande, Brazil, 2013) to calibrate its rating-curve equation. The SPM data presented here is the information estimated from the monthly riverine outflow for the Guaíba and Camaquã Rivers.

title: SPM estimates derived from MODIS-aqua data along Patos Lagoon - MODIS (2003 - 2019, Novoa et al. 2017)

description: Remote sensing has proved to be an effective tool for SPM studies in the Patos Lagoon. The ability to use this tool allows detailed analysis of spatial and temporal patterns and contributes to a better understanding of SPM dynamics. 17 years of daily MODIS-aqua data were used to estimate SPM concentration. The satellite scenes were atmospherically corrected and checked for quality of Remote Sensing Reflectance in a quality control system proposed by Wei et al. 2016. It consists of a scoring system ranging from 1 (perfectly acquired data) to zero (unusable). Values corresponding to scores lower than 0.6 were excluded from the data set. SPM was then estimate based on the semi-analytical algorithms proposed by Novoa et al. (2017; doi:10.3390/rs9010061). Data is available as averaged sample boxes from north to south of Patos Lagoon, rivers mouth, and lagoon inlet.

title: (Fig 3, page 49) Variations with depth of the SMOW Relative Deuterium/Hydrogen Ratio (DeltaD) values of Pacific Ocean manganese deposits

description: Initial data on the hydrogen-isotopic compositions in hydrous Mn minerals from various occurrences fall in a wide range from -298 to -84 per mil, relative to SMOW. DeltaD-values of todorokite and cryptomelane from Tertiary deposits show -89 and -150 per mil. 10 Angström-manganite and Delta-MnO2 from deep-sea nodules have relatively restricted DeltaD-values ranging from -96 to -84 per mil. The DeltaD-values for manganese bog ores from recent hot springs show almost -105 per mil. It is recognized that the isotopic values obtained for the deep-sea nodules and recent bog ores are slightly different ranged. Manganite and groutite are unique in their hydrogen-isotopic compositions, having the most depleted DeltaD-values ranging from -298 to -236 per mil. MnO(OH) minerals are more deuterium-depleted hydrous minerals than any other hydrothermal minerals from various ore deposits. Hydrogen-isotope fractionation factors between manganite and water were experimentally determined to be 0.7894, 0.7958 and 0.8078 at 150°, 200° and 250°C, respectively. the present experimental results indicate that if manganites were formed at temperatures below 250°C, under isotopic equilibrium conditions, most of the manganite mineralization in the Tertiary manganese deposits must have precipitated from meteoric hydrothermal solutions.

title: Carbon contents and isotopic compositions from the ODP Hole 161-974C near the center of the Tyrrhenian Basin (Table 1)

description: The modern Mediterranean Sea is oligotrophic, yet its sediment record contains layers of organic-carbon-rich sapropels at 21 ky (precessional) spacing that imply periods of elevated paleoproductivity that approached the high productivities of modern upwelling systems. Resolution to this paradox is provided by lines of evidence suggesting that the mode of primary productivity changed from one dominated by algae to one during times of sapropel deposition in which photosynthetic bacteria were important. We have made a high-resolution comparison of the organic carbon and nitrogen isotopic compositions of three sapropels and their background sediments in a 3-m sequence that corresponds to 1001 to 946 ka. Organic d13C values systematically increase from -26 per mil to -21 per mil and d15N values systematically decrease from ~4 per mil to &lt;0 per mil as organic carbon mass accumulation rates increase in the sapropel layers. The increase in carbon isotope values mirrors the increases in primary productivity and associated organic matter export indicated by the increased mass accumulation rates. The decrease in nitrogen isotope values implies major contributions of nitrogen-fixing cyanobacteria to the total marine productivity. The precessional minima with which sapropels coincide were times of wetter climate that stratified the surface Mediterranean Sea, increased delivery of soil-derived phosphorus, and evidently amplified microbial primary production. Our high-resolution study reveals several relatively rapid excursions into and out of the high-productivity mode that suggest that sapropel deposition was a climate-sensitive surface-driven phenomenon that was not accompanied by basin-wide stagnation.
