Day 20 - November 7, 2018


I don’t know if I’ve mentioned this, but we’ve named/are naming the seamounts! Anything that we map we name making our science discourse and discussions that much more interesting and clearer. The rift in the middle of the Rio Grande Rise is named Cruzeiro do Sol in Portuguese, which means Southern Cross, and is also the name for a constellation in the Southern Hemisphere. Our naming convention follows this theme of Southern Hemisphere constellation and stars. Thus we projected a constellation map onto our dredge sites, with the Southern Cross projected onto the largest seamount in the province, now named Crux Guyot. Hereafter, we named all the large massifs after constellations that are surrounding the Southern Cross, and the individual rises, seamounts, and escarpments are being named after stars in or around those constellations!

Our dredge today (Number 10) was interesting. As a testament to how volatile the sea can be, we had almost no wind, yet were completely taken by surprise while dredging by a strong current. We try to go in the straightest path possible, but this current pushed us far to port very quickly. The guys in the bridge got us back on our line and the dredge bucket didn’t get caught on anything, which is the most important thing.

On our way to the next dredge site, we started mapped a large seamount. We’ll dredge it later when we’re coming back, per our planned dredge route.
