The Cenozoic palaeoenvironment of the Arctic Ocean [PDF]

Nature, 2006
The history of the Arctic Ocean during the Cenozoic era (0-65 million years ago) is largely unknown from direct evidence. Here we present a Cenozoic palaeoceanographic record constructed from >400 m of sediment core from a recent drilling expedition to the Lomonosov ridge in the Arctic Ocean.

Ocean Arc: An Ocean Shot for the Arctic

Marine Technology Society Journal, 2021
Abstract Photography can be a powerful instrument for change. Combining scientific research, new imaging technologies equipped with Artificial Intelligence, and underwater photography, we'll share near- to real-time changes of biodiversity in the Arctic and highlight these rapidly changing and unique environments.

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]

, 2006
During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

Stability of the arctic halocline: a new indicator of arctic climate change

Environmental Research Letters, 2018
In this study, we propose a new Arctic climate change indicator based on the strength of the Arctic halocline, a porous barrier between the cold and fresh upper ocean and ice and the warm intermediate Atlantic Water of the Arctic Ocean.

An inventory of Arctic Ocean data in the World Ocean Database [PDF]

Earth System Science Data, 2018
The World Ocean Database (WOD) contains over 1.3 million oceanographic casts (where cast refers to an oceanographic profile or set of profiles collected concurrently at more than one depth between the ocean surface and ocean bottom) collected in the ...

Utilizing Colored Dissolved Organic Matter to Derive Dissolved Black Carbon Export by Arctic Rivers [PDF]

, 2015
Wildfires have produced black carbon (BC) since land plants emerged. Condensed aromatic compounds, a form of BC, have accumulated to become a major component of the soil carbon pool. Condensed aromatics leach from soils into rivers, where they are termed

Bromine measurements in ozone depleted air over the Arctic Ocean [PDF]

, 2010
In situ measurements of ozone, photochemically active bromine compounds, and other trace gases over the Arctic Ocean in April 2008 are used to examine the chemistry and geographical extent of ozone depletion in the arctic marine boundary layer (MBL ...

The Ocean Carbon Cycle in the Western Arctic Ocean: Distributions and Air-Sea Fluxes of Carbon Dioxide [PDF]

Oceanography, 2011
The Arctic Ocean is a potentially important sink for atmospheric carbon dioxide (CO2) with a recent estimate suggesting that the region contributes from 5 to 14% of the global ocean's net uptake of CO2.

The Law of the Sea and the Arctic Ocean

Arctic Review on Law and Politics, 2011
Rather than proposing new legal instruments for addressing the contemporary significant changes of the Arctic Ocean, both the 2008 Ilulissat Declaration and the 2010 Chelsea ministerial meeting reaffirm the five Arctic coastal States’ commitment to the ...

Future Arctic Climate Change in CMIP6 Strikingly Intensified by NEMO‐Family Climate Models

Geophysical Research Letters, 2023
Climate change in the Arctic has substantial impacts on human life and ecosystems both within and beyond the Arctic. Our analysis of CMIP6 simulations shows that some climate models project much larger Arctic climate change than other models, including ...
