Marine bio Camp - day 6 recap

Well, this year's Marine Biology Camp came to a close with a whale watching excursion with Capt. John Boats out of Plymouth, MA. Although our chances of seeing anything seemed slim with the heavy fog rolling in, our luck was good once we hit Stellwagen Bank and the fog cleared. Highlights from the the trip:

  • Saw five humpbacks up close, including two cow-calf pairs, as well as a couple of minke whales and a fin whale off in the distance

  • One of the humpback whales we saw was Salt, the first humpback to be given a name some 30+ years ago, and her new calf, Sanchal
  • .
  • Great bubble net feeding beahvior

  • Best of all, Sanchal gave us a show with a "spinning head breach" right in front of the bow of the boat. This was the first time I had ever seen a breach and was as amazing as I thought it would be!
Upon our return to campus, we gave the Marine Bio students their final exam. We'd been hyping it up all week long, scaring them into paying attention and taking notes, even offering bonus points for various things throughout the week. In the end though, the "final" was a fun scavenger hunt across campus, complete with a bucket for bringing back samples (e.g. an herbivorous marine gastropod, a piece of flotsam, a member of the phylum Arthropoda). No grades are assigned - everyone had fun, learned some stuff, did some things they never did before, and got a cool RWU Marine Biology t-shirt. A success by all accounts (excepting the one kid that left mid-week).

It was an intense week - I feel like we did an entire semester of a Marine Bio lab/field course in one week. I think I'll go to bed now and sleep for about three days!

Marine bio Camp - day 5 recap

Today's Itinerary:
Morning Session
Trawling on the 54' fishing vessel, the Captain Bert - students got to see the deployment of a smallish otter trawl and learn some fish biology while examining the haul;
Our catch included fluke, flounder, lobstahs, sea robins, scup/porgies, and squid;
Observe fluke dissection - examine internal anatomy and stomach contents (two recently eaten scup);

Afternoon Session
Winkler titrations of light/dark bottles from yesterday;
determine and graph primary productivity (gross and net) and respiration rates for surface and deep water;

Evening Lecture
Marine Mammals, given by yours truly (why me? cause our resident marine mammologist is on sabbatical and I lost the coin flip; thank goodness for wikipedia!)

Marine bio Camp - day 4 recap

Today's Itinerary
Morning session
Take RWU boats out for plankton sampling - one boat deploys a 150μm zooplankton net, the other deploys a 20μm phytoplankton net;
Using Van Dorn bottle, collect water samples and set-up primary productivity analysis (using the light/dark bottle technique);
In lab, use microscopes to examine the plankton samples - sketch and ID five phytoplankton and five zooplankton;
use spectrophotometers to measure chlorophyll concentration in samples filtered yesterday;

Afternoon session
Head to Fogland Beach for some fish seining along the shore and salt marsh;

Evening Lecture
Fish Biology

Highlight of the Day
Catching a 20-inch striped bass in the beach seine

Lowlights of the Day
1) Lion's mane stings
2) For tomorrow's Winkler titrations I wondered if I should use glass or plastic graduated cylinders. Are the high schoolers careful enough for the glass ones? I don't know...they're pretty fragile...and tippy (the cylinders, not the kids!)...oh what the hell, let them use the good stuff. Any bets on what I did while setting up? I decided to go with plastic.

Marine bio Camp - day 3 recap

Today's Itinerary:
Morning session
take RWU's two small boats (a 19' Lema Skiff and a 29' Master Marine) out on the Bay;
on one boat - take CTD and Secchi disk readings from three different stations; collect surface, mid-column, and "deep" water samples using a Van Dorn bottle (for chlorophyll analysis back in the lab);
on 2nd boat - deploy Van Veen Grab and small otter trawl, identify and discuss critters found

Afternoon session
discuss productivity, photosynthesis, and ways of measuring both;
process water samples collected in morning - for each sample, filter 1L through 0.5μ membrane, place membrane filter in 10ml acetone to extract chlorophyll, let sit overnight (will quantify chlorophyll spectrophotometrically tomorrow);
discuss what characteristics make a good graph;
create depth profiles using CTD data from morning (salinity, temperature, and dissolved oxygen vs depth);
interpret depth profiles and relate to the geography of the Bay;

Evening Lecture
Phytoplankton, primary productivity, and marine invertebrates (characteristics of major phyla) - presented by our two senior undergraduate camp assistants

Issue of the Day
Lost a kid. OK, not really, but one kid did decide that he hated the camp so much he didn't want to stay. So, his dad came by this evening, picked him and his stuff up, and took him home. Oh well. Maybe he was expecting dolphins and sharks or something.

Marine bio Camp - day 2 recap

Itinerary:
kayak in Ninigret Pond;
explore the salt marsh, tidal flats, eel grass beds, sandy beach;
search for, find, and identify critters, discuss their ecology/natural history;
discuss sedimentation, local geology, glacial past, anaerobic decomposition, hydrogen sulfide production;
visit rocky intertidal zone at Beavertail State Park;
discuss important physical and biological factors at play here;
examine zonation;
search for, find, and identify critters;
compare and contrast with sandy beach environment;

Problems encountered:
Shuttle bus with students taking the long way around, getting stuck in morning rush-hour traffic;
kayak outfitter unable to unlock kayaks -> go out and rent bolt cutters -> cut lock;
kid from CA forgetting his parent-signed kayaking release form;
RWU shuttle failing to return to pick us up to take us to the rocky intertidal (they didn't see the second destination on the shuttle request form);
hung around kayak center parking lot for a couple of hours waiting for RWU security to "do their best to get someone out to pick us up";
had approximately 40 minutes at rocky intertidal;
one bloody shin and one smashed toe (neither mine);

At least it didn't rain on us. And I didn't lose anyone.

Kayaks, Winklers, and Otter Trawls....oh my!

Today was the start of the RWU Summer Marine Biology Camp, a one-week, intensive, hands-on marine biology experience for high school kids. And I'm running it. Or rather, I'm co-running it with Scott Rutherford, our resident geologist. Today, 15 students arrived with their parents (well, technically, 14 arrived with parents, 1 flew in solo from CA), got settled into their dorm rooms, and got oriented to the program. Our week is packed full - so much so that I think I may not see my wife and kids until Saturday. Sorry, Linda! Here's a quick run-down of some of the things happening the week:


  • kayaking at Ninigret Pond - we'll explore this coastal lagoon (aka salt pond) and associated habitats (salt marsh, sand/mud flats, barrier beach, eel grass beds), keeping an eye out for as many critters as we can

  • tidepooling at Beavertail State Park - a great, wave-swept, rocky intertidal area - perfect for observing zonation

  • using a small, hand-deployable CTD to create water column profiles in Mt. Hope Bay (a part of Narragansett Bay)

  • using Van Dorn bottles to collect water samples at various depths for chlorophyll analysis

  • phyto- and zooplankton tows and then some microscope work to see what we caught

  • investigation of primary productivity using light and dark bottles and Winkler titrations (if I can find the burets!)

  • fish seining at a local beach - we should find plenty of silversides, mummichog, and sheepsheads, among other things

  • deploying an otter trawl off the 54' fishing-cum-research vessel, the Captain Bert - I am really looking forward to this one as I have never done or seen this before - we should pull up a good variety of critters, hopefully with minimal harm/bycatch

  • whale watching on Stellwagen Bank - a good way to end the week.

Just so you don't think the students are having all fun this week, there are also evening lectures after dinner that they have to endure and a final exam at the end. I'll be giving a lecture later in the week on marine mammals (!!) in prep for the whale watch (more on this later). Should be an exhausting, but fun week!
