Abstract Concern over plastic pollution of the marine environment is severe. The mass-imbalance between litter supplied to and observed in ocean currently suggests a missing sink. However, here we show that interior conceals high loads small-sized debris which can balance even exceed estimated inputs into since 1950. combined mass just three most-littered plastics (polyethylene, polypropylene, polystyrene) 32–651 µm size-class suspended top 200 m Atlantic Ocean 11.6–21.1 Million Tonnes....
The biological carbon pump, which transports particulate organic (POC) from the surface to deep ocean, plays an important role in regulating atmospheric dioxide (CO2) concentrations. We know very little about geographical variability remineralization depth of this sinking material and less what controls such variability. Here we present previously unpublished profiles mesopelagic POC flux derived neutrally buoyant sediment traps deployed North Atlantic, calculate length scale for each site....
Plastics and other artificial materials pose new risks to health of the ocean. Anthropogenic debris travels across large distances is ubiquitous in water on shorelines, yet, observations its sources, composition, pathways distributions ocean are very sparse inaccurate. Total amounts plastics man-made shore, temporal trends these under exponentially increasing production, as well degradation processes, vertical fluxes time scales largely unknown. Present circulation models not able accurately...
The aim of this study was to assess the abundance microplastics in gastro-intestinal tracts three commercially important fish species UK, determine whether catch location, feeding habits and size influence amount within fish. Fish were collected from two rivers UK: River Thames Stour (East Anglia). sites one site Stour. Species selected European flounder (Platichthys flesus), whiting (Merlangius merlangus), Atlantic herring (Clupea harengus), chosen represent benthic pelagic habits. Across...
Climate variation affects surface ocean processes and the production of organic carbon, which ultimately comprises primary food supply to deep-sea ecosystems that occupy ≈60% Earth's surface. Warming trends in atmospheric upper temperatures, attributed anthropogenic influence, have occurred over past four decades. Changes temperature influence stratification can affect availability nutrients for phytoplankton production. Global warming has been predicted intensify reduce vertical mixing....
Synopsis Evidence has accumulated over the past twenty years to suggest that deep-sea environment is not as constant was at one time thought, but exhibits temporal variations related seasonally in overlying surface waters. Recent results from deep-moored sediment traps this coupling mediated through sedimentation of organic material, while observations Porcupine Seabight indicate region, least, there a major and rapid seasonal deposition aggregated phytodetritus sea-floor slope abyssal...
It is premature to sell carbon offsets from ocean iron fertilization unless research provides the scientific foundation evaluate risks and benefits.
Abstract Understanding the influence of anthropogenic forcing on marine biosphere is a high priority. Climate change‐driven trends need to be accurately assessed and detected in timely manner. As part effort towards detection long‐term trends, network ocean observatories time series stations provide quality data for number key parameters, such as pH , oxygen concentration or primary production (PP). Here, we use an ensemble global coupled climate models assess temporal spatial scales over...
Abstract A closed eddy core in the Subantarctic Atlantic Ocean was fertilized twice with two tons of iron (as FeSO 4 ), and 300 km 2 patch studied for 39 days to test whether fertilization enhances downward particle flux into deep ocean. Chlorophyll a primary productivity doubled after fertilization, photosynthetic quantum yield ( F V / M ) increased from 0.33 ≥0.40. Silicic acid (<2 µmol L −1 limited diatoms, which contributed <10% phytoplankton biomass. Copepods exerted high grazing...
Progress to reduce plastic pollution has been painfully slow and the consequent damage natural environment human health is likely increase further. This because views ways of working four distinct stakeholder communities are not sufficiently well integrated. (1) Scientists, (2) industry, (3) society at large (4) those making policy legislation must in future find work together.
