Millions of metric tons plastics are produced annually and transported from land to the oceans.Finding fate plastic debris will help define impacts pollution in ocean.Here, we report abundances microplastic deepest part world's ocean.We found that hadal bottom waters range 2.06 13.51 pieces per litre, several times higher than those open ocean subsurface water.Moreover, sediments Mariana Trench vary 200 2200 distinctly most deep sea sediments.These results suggest manmade have contaminated...
Marine sediments have been considered to be a major sink for microplastics, yet the pollution history of microplastics recorded in these remains poorly understood.Using combination 210 Pb chronology and quantification undisturbed sediment cores, here we established forty-year northern South China Sea (SCS), largest marginal sea western Pacific.We found that SCS commenced 1980s.A dramatic increase microplastic abundance about 1998 marked an important breakpoint contamination.Since then,...
Unraveling the mysterious pathways of pollutants to deepest oceanic realms holds critical importance for assessing integrity remote marine ecosystems. This study tracks transport into depths oceans, a key step in protecting sanctity these least explored By analyzing hadal trench samples from Mariana, Mussau, and New Britain trenches, we found widespread distribution organophosphate ester (OPE) flame retardants but complex pattern OPE regions. In Mariana Trench seawater column, concentrations...
Abstract Water‐mass transports in the vast and seemingly quiescent abyssal ocean, basically along topographically‐guided pathways, play a pivotal role Earth's climate. The pulse of circulations can be taken with observations at topographic choke points. Yap‐Mariana Junction (YMJ) is exclusive point through which Lower Circumpolar Deep Water (LCDW) enters Philippine Sea. Here, we quantify LCDW transport its variability based on mooring YMJ Mariana Trench (MT). flows northward toward Sea as an...
Persistent organic pollutants (PCBs and PBDEs) were analysed in sediment core samples (0-2 cm) from the southern Mariana Trench at water depths of 7000-11000 m. ∑PCBs concentrations ranged 931 to 4195 pg/g, far higher than those recorded before marine sediments shallower depths.Toxic Equivalence (TEQ) dl-PCBs 0.650 -14.9 which is most surficial <500-2500 m ocean depth, recovered semi-industrial industrial areas.However, ∑ 8 PBDEs values (averaging ~136 pg/g) lower shelf areas past...
Seaweed cultivation contributes to coastal carbon sequestration making it a compelling strategy mitigate global climate change. Porphyra (commonly known as nori) is an economically important seaweed have high release rates for biogenic dissolved and particulate organic matter (DOM POM). However, the impact of on dynamics remains unclear. To fill this knowledge gap, we conducted investigations examining quantity optical properties DOM POM, microbial community structures relevant environmental...
Abstract. By analyzing dataset derived from four moorings during spring 2022, this study provides direct evidence that near-inertial waves (NIWs) can be largely enhanced by a passing cyclonic eddy (CE) in the northwestern South China Sea. Results show enhancement of NIWs mainly occurred at north side CE due to asymmetry structure. In vertical, concentrated above 200 m and reached peaks around 100 m. Significant energy transfer rates between appeared same depth reach up 6×10-10 m2/s3 CE’s...
Abstract Ocean circulation in the Challenger Deep is rarely investigated due to sparse observations. Based on hydrographic data collected by two super‐deep Chinese “Sea‐Wing” gliders during September–October 2018, we analyzed water properties and ocean structures this trench. Results showed that horizontal distribution of approximately a three layer structure, changing from northeast‐southwest structure north‐south then an east‐west as depth increases 3,000 7,000 m. This joint result uplift,...
The Challenger Deep (CD) is the deepest known hadal trench in world. Due to challenges data sampling at extreme ocean depths, Lower Circumpolar Water (LCDW) transport and circulation structure CD remain unclear. By analyzing from an extra-deep current meter mooring array, here we find a three-layer CD, transitioning downward westward LCDW flow (about -1.866 ± 2.953 Sv, 1 Sv = 10
Thirty conductivity-temperature-depth profiler casts in the Challenger Deep were conducted during four cruises from December 2015 to February 2017. Two took place summer, and two winter. The results demonstrated that water characteristics varied seasonally. temperature minimum values same between cruises, but its depth was noticeably shallower winter than summer. θ-S diagram indicated deep is more saline summer at potential temperature. Mixing intense 5000 6800 m dissipation rate eddy...
The Antarctic Bottom Water (AABW) current plays a crucial role in storing and transporting heat, water, nutrients around the world. However, it is impossible to monitor AABW Plio-Pleistocene by direct measurement. Hence, abyssal erosion was usually chosen as an effective indicator of presence Indian Eastern Pacific Oceans during that period. Here, we report high-resolution magnetostratigraphy gravity core, JL7KGC-01A from south Mariana Trench, northwest Ocean. main results are follows: (1)...
An intensive observation and a three-dimensional finite-difference model of Environmental Fluid Dynamic Code were used to study saltwater intrusion in the Pearl River Estuary. The simulation was carried out for December 2007 February 2008, which covered situ observation. forced by observed winds, tidal elevation at open boundaries, river discharges from eight inlets agreements with verified terms current, salinity tide elevation. Using computed residual current also calculated estimate...
