C.C.B. 2015

A wild ride

We just finished our last week for the CCB 2015 field season, which also means we finished our field work for the North Atlantic right whale mother/calf research project. Pretty crazy and a little bit weird for me since this has has been my primary focus for the last three years with the Parks Lab. I will say, we definitely went out with a bang. Our last week on the Cape consisted of 5 days out on the water and 8 successful tag deployments. Granted, 4 of those lasted ~ 5 minutes or less…but we still got the tags on and that is the hardest part. The other 4 tags however varied from pretty good to amazing, with 2 lasting ~25 minutes, one lasting an hour, and our final tag out on the very last day staying on for 4 hours! Our best deployment for the entire project by FAR, and our best week for the entire project too.

Not only did we have great success tagging, but we had a good time too. We got to experience some of the best moments any right whale researcher can hope to experience, such as finding yourself surrounded by a dozen high skim feeding right whales and getting curious approaches from calves.

As much as whale research can be frustrating and difficult, those moments make it all worth while and there is nothing else I would rather do. I sure am gonna miss those “little” guys. Until the next project, the Selkie crew bids you adieu!

Bon Voyage, Balaenids!

With two successful thesis defenses behind us, Hannah and I decided to head for the coast and join Dana and the rest of the right whale crew in Cape Cod for the weekend.  There was only enough room on Selkie for one of us at a time, so Hannah went out Saturday, and I waited for Sunday to go see my favorite balaenid whales.

The weather was gorgeous, and we found our first mom-calf pair of the day (#2145 and calf) within an hour of leaving the dock.  Unfortunately, 2145 wasn’t being terribly cooperative, even when we took long breaks between tagging attempts.  It also didn’t help that she was so concentrated on her food: feeding whales can be particularly difficult to tag because they only leave their rostrums poking out during high skim feeding.

It’s always surprising that such a big animal can keep so much of its body underwater and leave just the tiniest bit poking out.

This is about as good as it gets in terms of looking into a whale’s mouth! Not awesome for tagging their backs, though.

2145’s calf was mimicking mom and skim feeding right behind her. Too cute!

We were just about to leave the area and leave 2145 to her own devices to survey for more whales when another mom-calf pair showed up!  1604 was feeding by herself, which made things tricky because without the visual cue of a calf right next to the mom, it can be hard to pick out who’s who.  Luckily Grace recognized her as a mom, and we were able to get a solid tag placement on her back!

Alex landed this fantastic tag placement on 1604!

The tag stayed on for about a half hour before coming off, and we then decided to head north where we had heard of a sighting of yet another mom-calf pair, 1703 (“Wolf”) and her calf.

We observed Wolf and her calf for about an hour and a half, and they were traveling fairly quickly and not really taking breaks that suggested they were in the mood to be approached.  Since we had already had a successful tag deployment and we were beginning to edge into twilight, we decided to head back to the dock and call it a day.

So in total, we saw three mom-calf pairs and probably 15-20 other individuals in our little corner of Cape Cod Bay.  Combined with the near-perfect sea conditions, not too shabby for my last day of right whale fieldwork as a member of the Parks Lab.

I sure am going to miss this.

Feeding time

Since we started our 2015 Cape Cod Bay field season, the right whales have been few and far between. They have been scattered about the Bay and in pretty low numbers. It also didn’t appear as if there was much food here and we didn’t see any of the high skim feeding that I have begun to associate with the Bay (see this previous blog post to see read more about skim feeding in right whales, and this post to see photos of a calf trying it out). But things are starting to look up it seems. The weather on Saturday was absolutely beautiful, and we often found ourselves in a sea state 0 or 1. Spectacular.

We searched around for more than half of the day to try and locate a mom/calf pair, but as it got later and later we made the decision to tag a single animal rather than go home with no data at all. Any data is precious and valuable, especially for a population this endangered! So we went to a small aggregation of feeding whales in the southern end of the Bay and picked one that was so preoccupied with subsurface skim feeding that it didn’t even seem to notice us sidle right up alongside it. It was an ideal situation, the perfect approach, and a solid tag attachment. In other words, it couldn’t have gone smoother.

As Alex so eloquently put it, tagging has two anxieties: getting the tag on, and getting it back! Once all the excitement of the deployment subsides, we then have to stay with the whale and track the tag.

This is always the worst part for me…will it stay on? Will we find it? Is the tag recording properly? Is the transmitter functioning alright? So many things to stress about, and in the case of our tagging on Saturday, 1 hour, 38 minutes, and 1 second to do it. Then it fell off, we got it back on board safely, I checked that it recorded, and all was well with the world. Until next time.

100 miles

We would do a lot for data, not the least of which is a 10 hour day and a roughly 100 mile round trip. When we launched the boat yesterday, we were going “blind” since the planes weren’t surveying the Bay. So we decided to go east where there were whales a few days prior because it was worth a shot and gave us a good look at the eastern side of the Bay. When that proved uneventful, we headed north to where the Callisto was currently working with a handful of whales. Once there, we found a single whale that we stopped to photograph and we were able to readily ID him as #3530 (Ruffian), an 11 year old male. This whale is very easily identifiable due to a pretty massive scar across his back. Whatever happened to Ruffian was pretty horrible, but he somehow, thankfully, managed to survive.

After getting good photos of that guy, we got a call from the CCS plane who was flying north of Cape Cod Bay that day. They had a mom/calf pair, #1604 and calf, but they were pretty far away from us – 20 miles away in fact. Not only that, they were on the backside of the Bay, well outside of our normal range for our CCB field season. It was still early in the day, the waters were smooth, and the forecast for the remainder of the day looked good so we made a decision. We were gonna go for it.

Our day. The orange marker is where we launched the boat, the red marker is where we found Ruffian, and the green marker was the location given by the plane of #1604 with her calf. Quite a day! Photo cred to Google on this one.

When we got to the coordinates given to us from the plane, we started our search to relocate the pair. After a good half hour of searching, we started to lose hope. I even started to doubt I wrote down the coordinates correctly…I’ve never done that before, but there’s a first time for everything, right? This would be an unfortunate first. Honestly not 5 seconds after I said, “I hate whales” out loud to Alex, they popped up and we both said “there”! For the record, I don’t really hate whales. I love them. They are just maddening sometimes…

Ya know what makes it all better though? This:

The only bad part of the day was the 40 mile schlep home…but it was all worth it. Back at it tomorrow!

Patience and persistence pay off

I know I have mentioned it before, but I think I should stress the point again – putting a tag on a whale is HARD. I mean, let’s think about it. We are trying to put a small recording tag (in our case an Acousonde) which is about 9″ long on a living, breathing, has-a-mind-of-its-own animal that can be anywhere from about 15 ft in the case of calves to over 50 ft in the case of moms. On top of that, the tag is deployed from a carbon fiber pole that extends to about 26 ft. The tag is then attached to the whale with suction cups that must all sit nice and flat in order for it to stay for any extended period of time, and anytime something (ahem, a calf) bumps into it, the tag can and often does slide or pop right off. Now all this must be done from a boat in whatever sea state you might find yourself in while the animal is often moving. Yeah. That being said, when we finally do get a tag on it is obviously the result of quite a bit of skill, but also more than a fair share of patience and persistence. And luck. We had all of these things on Sunday, plus #1611 and calf up past Race Point.

Under our permit we are allowed just 3 tagging attempts on a pair in order to minimize any stress to the animals, so each failed attempt isn’t just a blow to our pride, it is one major strike against us. Our first attempt was a good one, but not successful. Not a huge problem, we have dealt with that before, so we waited a bit and then slowly moved back in. Suddenly the perfect moment presented itself – the calf came up right next to the boat, slowly and calmly. But we must remember that tagging is HARD and life is cruel, so what happened next? Oh the tag fell out of the holder and plopped into the water next to the calf of course. Then what? The calf came right back up in the same spot, ready for tagging again, the tag still bobbing around nearby. Oh awesome, then what? The calf did a nice dive with a little turn of the fluke, effectively getting me wet just to rub some salt in the wound. Ouch.

Well that was not a good moment, no. And I have never felt more like just crawling under a blanket and taking a nap. But we are field biologists, huzzah, so we pick ourselves back up and we move on to attempt number three obviously! Patience and persistence rewarded.

That’ll do. Until next time, I will be doing what I love most – analyzing data.

One more time

I am back in Falmouth for our 5th Cape Cod Bay field season – and our last. Not only is this our final CCB field season though, it is our last scheduled field season for the North Atlantic Right Whale Mom/Calf Project. Crazy, right?

I got in last week and we have made it out on the water once so far. The Center for Coastal Studies (CCS) plane was flying so we had aerial coverage of the Bay which is always a huge bonus. They also had a couple of their boats, the R/V’s Shearwater and Ibis, out on the water and the New England Aquarium‘s R/V Callisto was out too. With all that support, we had the Bay well covered. Even better news is that the right whales showed up to the party.

The lack of whales was a big concern for us coming in this year – the previous aerial surveys for the year have seen a handful of whales down near Rhode Island Sound, including #1611 (Clover) & calf, but few to no whales in CCB. So while only 17 right whales were spotted on Monday, that hopefully means the whales are starting to move in to their spring feeding ground. No one spotted Clover and calf, or any mom/calf pair for that matter, but that doesn’t mean they aren’t on their way. Now we can’t wait to get back out and get some tags on!
