Today I am observing the fieldwork methods of Museum scientists Jo Wilbraham (algae, including seaweed) and Mary Spencer Jones (bryozoans). We depart on the boat from St.Mary's to St. Agnes at 10.15am in calm waters, under clear blue skies.

 

St. Agnes is a beautiful island, with many interesting locations to collect specimens. We arrive at low tide, which is ideal for finding a diverse range of seaweed and bryozoan specimens. Jo chooses a beach 10 minutes walk east of the quay, where it is possible to wade far out. It takes a while, and some skilled rock climbing to reach where we are going but once we arrive at the tidal interface the diverse range of species is quickly apparent. We see a wide range of seaweeds, sea anemones and polychetes patiently waiting for the tide to come back in and relieve them from the stress of exposure to the mid-day August sunshine.

Jo seems quite happy with the spot and comments on the range of species whilst pulling collecting bags and knife out of her pocket and rucksack to begin collecting, making the most of the low tide. The method of exploring and collecting are surprisingly similar to the methods that I use when working in the landscape or on a residency, although the selection criteria and motivation differ considerably. Some of the specimens collected are Furcellaria, Bifurcaria bifurcata and Palmaria palmata.

 

By this point my walking shoes have flooded after being submerged in shin deep seawater and I am inspired to draw some of the collected species on dry land. I am also preparing for the drawing workshop of creative morphology (a method inspired by Goethe’s ‘Delicate Empiricism’) at Phoenix art studios in the evening.

The free drawing workshop is fully booked, and attendees will be almost exactly half Museum scientists and half St.Marys residents or visitors. Due to the demands of fieldwork some of the Museum scientists are late, which means they have a bit of catching up to do. The workshop builds up observational drawing techniques that prepare the individual for a creative exploration of the morphology of the specimen.

 

Creative morphology drawing workshop

 

The group produce some very interesting drawings and discussions. One scientist remarks that they did not expect drawing to have method, rather that it was something they associated with scientific work. This point was important as it helped the scientist to acknowledge artistic research and methodology.

 

Another scientist remarks that drawing helped them to identify important characters of the specimen, and to engage with it. This was helpful as it led to a discussion of the values of drawing and photography/SEM technologies in scientific work. We end the workshop by considering the relationship between the practice of creative morphology and creative evolutionary processes.

After the drawing workshop I put a few questions to Jasmin Perera, an entomologist at the Museum:

GA: Do you feel the method helped you to 'know' or think about the specimen in a new or different way? If so, could you try to describe this difference?

JP: Yes the method did make me think a lot more about the specimen. It made it far more memorable structurally. There are parts that I would never have thought of analysing so much that I now know exist, which is great because I would feel far more confident in identifying the specimen if I came across it in future.

 

GA: Do you feel that the method helped you to deepen your engagement with the specimen?

JP: I think I did engage a lot with the specimen, however I feel I get a similar experience when identifying flies under the microscope as the keys we have to follow go into details as little as the length and direction of the little hairs on their body.

 

GA: Do you think this method could be useful in your scientific or artistic work? If so, how?

JP: I would find this method useful in a scientific environment as it would really make me remember any specimen I came across. Especially by pulling the specimen apart, figuring out all the bits that put it together.

 

After the drawing workshop I visit the Museum field station at the Garrison, St.Mary’s, where I find Jo sorting through the day's collections, soaking and pressing before carefully arranging on a herbarium sheet. The sun is setting, the team is tired and tomorrow awaits...the marvellous world of insects!

Breakfast was sausages – yes! Salty and oily they took my good friends rice and beans to a whole new level.

Today we set off from our hut, to the camp we are going to stay at for the next two days – N 09 08 09.4, W 082 57 38.4 are the co-ordinates: view on a map.

 

Our route took us along the river.

We walked for a couple of hours before climbing up to a point called Jardin. This area is completely different from anything I have seen so far on the trip – it’s a peat bog and is dominated by tree ferns that have islands of mosses, lichens and sedges growing around them. It was a rare break in the forest canopy and there were some spectacular views.

It was a really challenging crossing - impossible to know whether your next step was going to hold fast or leave you knee deep in the bog.

We then dipped backed down through the forest – not so much a trail as a thrash through the bush!

Once at the camp, I set up the equipment for sending you my post - solar charger and satellite phone - and made a little tour of the camp.

On the way here I saw the first sign of a wild cat – this is Ocelot poo, apparently!

Species of the day goes to Neil (though Alex is making a spurious claim!). It is in the genus Pilea (in the nettle family) and Alex thinks it may be a new species! He is a world expert in the nettle family and, in particular, this genus - although this looks similar to another species of Pilea it has a key difference in that the leaves are of equal size to each other as opposed to being different sizes.

 

If it is a new species Alex will be able to publish a description of it and give it a name, but he can only be sure that this is a new species once he has checked it against similar species housed in herbaria.

This really highlights the importance of the trip and of collecting in general. In order to know exactly what is in the park and make as complete a check-list of the species as possible, we have to know what lives here. These specimens will be available for future generations, who may have other uses for the data they provide.

 

Of course, it is important not to collect too much, we rarely collect a whole plant and always make sure we don’t collect without the correct permits which are provided by the Costa Rican government.
