I am an Earth & Environmental Science graduate student at Columbia University advised by Ryan Abernathey. I've compared averaged bottom temperatures within the Weddell Sea region from ECCO's dataset, as well as from the World Ocean Atlas 2018 datasets for two separate time periods (1981-2010 and 2005-2017). Below I have attached a figure of ECCO and WOA's bottom temperature spatial distribution as well as their difference. From the figure you can see that ECCO is overall warmer than the observational dataset. I am emailing to ask if you may know the reason why ECCO is representing a 0.5-2˚C warmer temperature bias. I still consider myself a novice user of ECCO so I was hoping you may shed some light on this. I would appreciate any insight, and thank you for your time.</div><div class=""><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div class=""><br class=""></div><div class=""><font face="trebuchet ms, sans-serif" class=""><br class=""></font></div><div class=""><font face="trebuchet ms, sans-serif" class="">Best,</font></div><div class=""><font face="trebuchet ms, sans-serif" class=""><br class=""></font></div><div dir="ltr" class=""><font face="trebuchet ms, sans-serif" class="">Shanice T.
