Please be aware of this scheduled interruption so that you can plan your work accordingly. ...

To improve the accessibility of data collected through NERC-funded research, or managed by NERC data centres and our collaborators, a NERC programme ( Constructing a Digital Environment ) are collecting feedback on the user experience (UX) to improve the navigation of various web portals to assess these data. This is done via a series of events called the NERC Environmental Data Discovery Trails. ...

The properties of our oceans are changing. The Southern Ocean absorbs more heat than any other ocean and as a consequence of climate change, it is warming at an alarming rate. Warming oceans lead to a decline in Antarctic sea ice, increased ocean freshening, sea-level rise, reduced oxygen and CO2 uptake and slow the vertical exchange of waters. This may bring about increased food scarcity, diseases, extreme weather events, loss of coastal protection, and more. It is therefore extremely important to have a detailed understanding of what could happen in the future with a Southern Ocean that is warmer, less salty and is circulating in different ways. ...

Unfortunately we are still having recurring problems with the Elastic Tape system. This has resulted in further failures of both ingesting and retrieving data. We are actively investigating this, in conjunction with our colleagues in the Scientific Computing Department (SCD). In particular our SCD colleagues have spent a lot of time trying to remedy this problem. ...

Dear users, Please be aware that due to scheduled network maintenance carried out by our host organisation, there will be a series of brief interruptions to network connectivity (a few seconds each) today, Wednesday 10th March 2021, between 09:00 and 10:30. These will affect network connections to the RAL site (and hence JASMIN and CEDA services), so may result in disconnected terminal sessions, interruptions to processing or data transfers in progress or availability of services. We are informed that the interruptions will also affect connections made using the Optical Private Network (OPN) connections to Leeds, Edinburgh and the Met Office. ...

The scheduled maintenance that happened yesterday, Tuesday 2nd March 2021, is now completed. Most JASMIN and CEDA services are back running as normal. However, there are ongoing issues related to access to MASS. We are working on resolving this ASAP. ...
