With an exponential growth in publications, are we advancing ocean science faster than ever before? As EiC @jgroceans.bsky.social I see better analyses on bigger data, but often at the cost of reflection on previous studies and of articulation of the most important gaps in our understanding.

This is oceanography the hard way. Before any instruments or samplers are deployed, we hot water drill an access hole through several hundred metres of ice shelf. Don't dilly-dally though, freezing closes the hole in a day or two.
