The importance of ecological accommodation space and sediment supply for cold-water coral mound formation, a case study from the Western Mediterranean Sea
No full textBy comparing the sedimentary parameters between two sediment cores that collected from coral ridge and adjacent seafloor (southern Alboran Sea, western Mediterranean Sea), we reconsructed the sedimentary process during the mound formation. Furthermore, we provide the first conceptual model of coral mound formation that highlights the role of coral-derived ecological accommodation space and sediment supply. The dataset provide the grain size, matrix sediment bulk dry density, sediment composition and associated accumulation rate of the matrix sediment from the two sediment cores. Besides, the comparison of average grain-size distribution and accumulation rate of siliciclastic sediment are provided

No full textProcessed physical properties measured on sediment core GeoB19940-2
No full textSound knowledge about the petrophysical characteristics of a sediment core is a prerequisite for any subsequent paleoenvironmental study relying on sediment proxies. Physical properties of whole-round sediment cores are acquired as a first step of sediment core description, prior to slicing of sediment cores into two halves. Here, we present processed physical-properties data of core GeoB19940-2 acquired with a Geotek MSCL-S system on the unsplit core, retrieved during RV Maria S. Merian expedition MSM44 to West Greenland/Baffin Bay in summer 2015. Cores were processed according to the standard protocol given by the manufacturer Geotek Ltd

Occurrences of fossil planktonic foraminifera in cores PC-11 and ND-2
No full textWe investigated fossil planktonic foraminifera from cores ND-02 (Nakdong River delta) and PC-11 (inner shelf off southeast Korea), to assess millennial-scale variations in the surface oceanography. The coiling ratio of Neogloboquadrina pachyderma shows five millennial-scale near-cyclic variations (~8.7-8.3, ~7.5-6.2, ~4.7, ~2.8 and ~0.5 ka) since ~9 ka. These variations are similar to warm-water diatom variations at the Oki Ridge where a cyclicity of ~1.6 kyr is present, possibly associated with a Bond event. By contrast, the near-cyclic variations in our planktonic foraminiferal record were not fully consistent with the reported intensity variations of the Tsushima Warm Current in the East Asian margin and the warm Kuroshio Current in the Northwest Pacific. Our records from southeast Korea seem to reflect the more regional oceanographic variations in the marginal seas of East Asia. We suggest that the coastal upwelling of the subsurface cold water along the southeast coast of Korea plays an important role in generating near-cyclic variations of warm-water biota. These variations may have a connection to the Bond event periodicity in the North Atlantic Ocean
Bulk organic geochemistry (TOC, TN, d13C, d15N) of suspended river sediments from Chilean Patagonia
No full textThis dataset presents bulk organic geochemical data (TOC, TN, d13C, d15N) obtained by EA-IRMS analysis on 16 suspended river sediments from vertical profiles in four of the largest rivers of Chilean Patagonia (44-48°S). The samples were collected in November 2011, i.e., in Spring, when river discharge is the highest. Surface samples (10 cm depth) were taken with a bucket, and deeper samples were collected with a horizontal WaterMark® 5L sampling bottle equipped with a depth/pressure sensor. All the water samples were stored in pre-rinsed I-chem cubitainers and filtered within 48 hours using a pressurized filtration system equipped with a 90 mm diameter PES membrane (pore size 0.22 µm)
