(*If you missed my first post on my JOIDES Resolution adventure, I encourage you to start with DrGw390 – Week of quarantine. All posts will be tagged with #DrGw390.)

We spent from May 11 thru May 18 at Site U1557, Hole U1557D. This post has a collection of my tweets from the coring at our second site for Expedition 390, and our first WOW (waiting on weather) event.

We started May 11th moving in DP (dynamic positioning) mode to Site U1557. We arrived at Hole U1557D at 1436 on the 11th. Time to send the pipe down to prepare for coring. In the meantime, there were more sites for me to explore around the ship.

May 12th was a date for RCB coring to begin at our new site – and for a new friendship to be made…

Made a friend today! @theJR mascot, Patrick the Safety Penguin. pic.twitter.com/kR9izCx1PE

It’s a challenge to keep on top of everything happening back home when you are on the water. And sometimes, there’s just nothing you can do about a request that comes in.

When your university library issues an immediate recall notice on a book you have checked out, but you are still out to sea for another month…. @theJR #EXP390 #DrGw390 pic.twitter.com/XK6WfX7CeG

I received a surprise shout-out on Twitter on this day! 500 Women Scientists is such an awesome organization – so glad to be a member and active in the Philadelphia Pod. Looking forward to reconnecting with the Philly Pod when I get back home!

Thanks for the shout-out, @500womensci! And I'm currently on board the scientific research vessel @theJR for the 2-month #EXP390 in the South Atlantic Ocean, helping advance/share our knowledge of the deep sea with other scientists, classrooms, & community groups. #ScientistAtSea https://t.co/tLCDkfKe4i

On May 13, the weather started picking up. All of our eyes became glued to https://earth.nullschool.net/

How the day started… how it ended. This wind map I’ve used quite a bit with students – never thought I’d be using it to see how close a cyclonic feature would be to me at sea! (@TheJR is at the green circle) #EXP390 #DrGw390 pic.twitter.com/O1YqYpuYCx

Another day of how it started & how it ended. We had to stop our drilling activities at 0530h (SAST), pull the drill bit out of the hole – and now, we "wait on weather" (WOW). On the ship, all eyes are on this… (@TheJR is at the green circle) #EXP390 #DrGw390 pic.twitter.com/NvBxAVybC3

While waiting on weather, I was able to wrap up my week-long Twitter takeover at @IAmSciComm.

I had such a great week over at @iamscicomm – what an amazing opportunity to share more about science communication about the sea, from the sea! More to come back on this account as I'm just past the halfway point of my time on @theJR #EXP390 #DrGw390 https://t.co/tkmk2dfvMX

Our WOW period coincided with a total lunar eclipse. I tried so hard to stay awake for it. But we all had problems trying to figure out the time zone we were in and when it would appear. I made it to 3:30AM but had to go back to bed. Despite someone knocking on my door at 5:30AM to get up and see it, I never heard them. Oh well, maybe next total lunar eclipse…

There’s going to be a total lunar eclipse this evening – but this view from @theJR in the South Atlantic isn’t so bad…. #EXP390 #DrGw390 pic.twitter.com/lMUD9B837B

In addition to @IAmSciComm, this was my second time doing a one-day guest post on the American Geophysical Union’s Instagram account! It was also nice that our WOW period ended and we restarted coring.

Thank you @theAGU for allowing me to be a #GuestGrammer today over on your @instagram channel! Check out my post where I describe what I'm up to as a science communicator/educator on @theJR for #EXP390 #DrGw390 #SciComm @AGU_SciComm https://t.co/Gb3XydNEKj

Earlier in the expedition, we had one scientist that was interviewed by one of his local television news stations. Today was a special webinar for the international series Pal(a)eoPERCS, featuring three of our early career paleo-researchers (and amazing people that work the day shift with me!).

It was so enjoyable to help these three early career paleo-scientists during today's @PalaeoPERCS webinar from @theJR! Remember the names Andrew McIntyre, Claire Routledge, and Yi Wang – so much exciting research being done by these three, & more to come in the future! #EXP390 pic.twitter.com/bBb22NLMpS

Some days I don’t get the images posted that I took them, but this moon pool photo was too good to let it not be posted!

Got to see the moon pool the other evening on @theJR! This is the hole in the bottom of the ship that allows us to send our drill bit & pipe down to the ocean floor to collect sediment/basement material. (scale = 22 feet wide) #EXP390 #DrGw390 pic.twitter.com/t7sRTf2Oqi

May 18 was our last day at Site U1557. Next up – our final site, U1559.
