Rates of relative sea-level rise during the final stage last deglaciation, early Holocene, are key to understanding future ice melt and change under a warming climate1. Data about these rates scarce2, this limits insight into contributions North American Antarctic sheets global Holocene. Here we present an Holocene curve based on 88 data points (13.7-6.2 thousand years ago (ka)) from Sea (Doggerland3,4). After removing pattern regional glacial isostatic adjustment caused by melting Eurasian...
Proposed harvesting of polymetallic nodules in the Central Tropical Pacific will generate plumes suspended sediment which are anticipated to be ecologically harmful. While deep sea is low energy, it also can highly turbulent, since vertical density gradient suppresses turbulence weak. The ability predict impact limited by scarcity in-situ observations. Our observations show that low-energy environment more than four kilometres below surface ultimately becomes an order magnitude energetic for...
The anthropogenic impact of polymetallic nodule harvesting in the Clarion-Clipperton Fracture Zone is expected to strongly affect benthic ecosystem. To predict long-term, industrial-scale mining on deep-sea environment and improve reliability sediment plume model, information about specific characteristics particles needed. Discharge simulations mining-related fine-grained (median diameter ≈ 20 μm) plumes at concentrations 35–500 mg L–1 (dry weight) showed a propensity for rapid flocculation...
Abstract Collections of the amphipod genus Oedicerina were obtained during six expeditions devoted to study deep-sea environments Pacific Ocean. The material revealed four species new science. Two (Oedicerina henricisp. nov. and teresae sp. nov.) found at abyssal depths central eastern in Clarion-Clipperton Zone; one claudei was recovered Sea Okhotsk (north-west Pacific), lesci abyss adjacent Kuril-Kamchatka Trench (KKT). differ from each other known by shapes rostrum, coxae 1 4, basis...
A multiproxy record has been acquired from a piston core (SO139‐74KL) taken offshore southern Sumatra, an area which is situated in the southwestern sector of tropical Indo‐Pacific Warm Pool. The high‐resolution data sets (X‐ray fluorescence, total organic carbon, and C 37 alkenones) were used to track changes paleoproductivity, freshwater budget, sea surface temperature (SST) climate system at orbital time scales over past 300 ka. Our paleoclimatic show that enhanced marine...
Abstract. The largest and commercially appealing mineral deposits can be found in the abyssal sea floor of Clarion-Clipperton Zone (CCZ), a polymetallic nodule province, NE Pacific Ocean, where experimental mining is due to take place. In anticipation deep-sea impacts, it has become essential rapidly accurately assess biodiversity. For this reason, ophiuroid material collected during eight scientific cruises from five exploration licence areas within CCZ, one area being protected (APEI3,...
