A crazy amount of heat has accumulated in the Equatorial Pacific Ocean over the past two months.
Hold on to your hats when this reaches the surface with the next El Niño.
Y-axis shows depth, X-axis shows degree longitude (one degree equals 111 km) and colors temp anomalies.

Last paper of the year! A new nudibranch species as a result of exploring the feeding ecology of hydroid feeding nudis in Thailand! Since I started this work almost 10 years ago, there's finally been some trickling of global nudi ecology research which is great!
