Arctic sea ice decline
Understanding the effect of Arctic sea ice decline on the Atlantic meridional overturning circulation

The Arctic sea ice decline may explain the suggested slow-down of the Atlantic meridional overturning circulation and the persistence of the Warming Hole.

Monthly SST anomalies 1920–2016
The complex relationship between El Niño and the California Current System

New research confirms that links between warm and cool years in the California Current System and El Niño are important but imperfect.  

Southern Ocean upwelling pathways
Three-dimensional Southern Ocean upwelling pathways

A new study combines ocean observations with three state-of-the-art ocean models, revealing the full three-dimensional pathway of deep water to the surface of the Southern Ocean for the first time.

Understanding drivers of past and future sea level rise along the northeast US Coast

A new study helps clarify how past and future coastal sea level changes are related to local winds and large-scale ocean circulation.

SST and total soil water distribution over North America
Atlantic/Pacific climate contrast affects multi-year predictability of US drought and wildfire

Researchers have developed a state-of-the-art drought and wildfire prediction system, showing the multi-year predictive skills of drought and wildfire conditions beyond the typical timescale of seasonal climate forecast models.

Differences in climate model simulations
The role of Antarctic sea ice in shaping modern and glacial deep ocean circulation

A recent study investigates the drivers of changes in deep ocean circulation across a range of modern and Last Glacial Maximum (~21000 years ago) climate modeling simulations, revealing biases in Antarctic sea ice formation.

Requests are now being accepted for up to one new US CLIVAR-sponsored working group for 2018. Submissions are encouraged from the US climate science community. All documents must be submitted by October 12, 2017. The next call for working groups will be in September 2018.

Apply by October 6: Ocean mesoscale eddy workshop

ocean eddies

On February 17-18, US CLIVAR will host a workshop to create a shared understanding of ocean mesoscale eddy interactions with the atmosphere. The workshop will be held in conjunction with the 2018 Ocean Sciences Meeting in Portland, Oregon, and limited to 50 participants. Applications are due October 6.

Sea level conference statement

By the numbers

The WCRP/IOC Sea Level Conference organizers seek signatories for the conference statement, based on input from the broad community. You can read about the conference in the daily highlights and a "by the numbers" graphic. 

Variations, Summer 2017

variations cover

The 2017 summer edition of Variations, with guest editor Sonya Legg (Princeton U.), is themed: "Polar ocean and sea ice interactions." This edition focuses on describing and understanding the interactions between ocean circulation and sea ice, in addition to highlighting new observational and modeling opportunities.
