Nice graph, I must have missed that one. Can you add the link for it?

I found it by [clicking on "images" in the same search](https://www.google.ca/search?q=%22sea+level+rise%22++melting+ice+expansion&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj9qt6qxL7XAhUGwmMKHe-EBGkQ_AUICigB&biw=711&bih=705&dpr=1.5). Dropping the image into [Google images](https://www.google.com/imghp) turned up the NASA link. (I may not know much about SLR, but I'm good at looking stuff up. :>) )

Thanks for updating the image source. It really does help show the complexity of the situation. Being good at looking things up is quite useful!

<p>Its a big number, difficult to estimate I assume. But is there a peer reviewed estimation (at current conditions) of the volume of daily or annual increase of water? </p>

I don't know if this helps, but since you have no response yet perhaps I can offer some thoughts.Your question is problematic due to the fact that volume itself is variable according to the temperature of the water.

This expansion due to warming literally changes the volume of the water, adding to the sea level rise. So glacial melt may be measured or estimated, but the change in sea level caused by this volume of water is variable; over time it will change temperature and expand. But this isn't straightforward either. [Nasa again](https://sealevel.nasa.gov/understanding-sea-level/causes/overview):
