Over the past decade a major initiative examined the chemical flux transfers from eastern UK Rivers to the North Sea as part of an ambitious community research programme, the Land Ocean Interaction Study (LOIS). In this paper, a compilation of data on flux and flux per unit area for five major river basins, the Tweed, the Wear, the Humber, the Great Ouse and the Thames is presented based on an extensive riverine monitoring programme within the LOIS. The compilation includes details on the fluxes of major, minor and trace elements as well as the nutrients and sediments. In the process, the flux inputs are related to the major tributary sources for these basins and compared with earlier studies based on complementary information for eastern UK Rivers entering the North Sea collected within the Harmonized Monitoring Scheme. The significance of the southern Humber Rivers to pollution fluxes to the North Sea is highlighted in relation to the predominance of urban and industrial sources.

Knowledge of spatial distribution patterns of biodiversity is key to evaluate and ensure ocean integrity and resilience. Especially for the deep ocean, where in situ monitoring requires sophisticated instruments and considerable financial investments, modeling approaches are crucial to move from scattered data points to predictive continuous maps. Those modeling approaches are commonly run on the macrobial level, but spatio-temporal predictions of host-associated microbiomes are not being targeted.

Understanding the spatial ecology of commercially exploited species is vital for their conservation. Atlantic bluefin tuna (Thunnus thynnus, ABT) are increasingly observed in northeast Atlantic waters, yet knowledge of these individuals' spatial ecology remains limited. We investigate the horizontal and vertical habitat use of ABT (158 to 241 cm curved fork length; CFL) tracked from waters off the United Kingdom (UK) using pop-up satellite archival tags (n = 63).

The recent sea ice changes in the Northern Hemisphere (NH), necessitate elucidating the sea ice variability over the past 2.6 million years (Ma), when the Earth's glacial cycles transitioned from ∼41 to ∼100 kyr periodicity, following the Mid-Pleistocene Transition (MPT) period (0.7-1.

Several wildlife species exhibit marked spatial variation in toxicologically relevant tissue concentrations of mercury across the Aleutian Islands of Alaska, most notably the endangered Steller sea lion (Eumetopias jubatus). To unravel potential environmental and trophic pathways driving mercury variation in this species of concern, we investigated spatiotemporal and ecological patterns in total mercury concentrations and stable isotope ratios of carbon and nitrogen from muscle tissues of twelve mid-trophic level prey species of the region (n = 1461). Dividing samples into island groups explained biogeochemical variation better than larger spatial resolutions, with Amchitka Pass and Buldir Pass acting as strong geographic break points.

To achieve accurate monitoring of water leakage in tunnels, a new vertical graphene sensor is designed and developed. The sensor operates on the principle that the superabsorbent polymer (SAP) swells dramatically upon water absorption. This swelling induces deformation in the vertical graphene (VG) thin film, highly sensitive to such changes.
