By Peggy Liebig - NDP Intern Jun-Jul 2016
My 6 week internship with the NDP started with a couple days of theoretical presentations about what we are going to work on
for the next 6 weeks. Each week had a different theme which we were learning
the theory and practice about. Then we got to work...
Each day two of the
four interns would get on the boat in the morning (weather dependent,
unfortunately the weather was really bad the time we were there) while the
other two stayed in the office to do Photo-ID. When coming back from the boat
we entered the collected data into the spreadsheets. Also there would be one of
us going on a tour boat to gain some additional opportunistic data and how the
tour boats are interacting with dolphins and seals.
We also did a bird
survey almost every day to count the different species of birds in the lagoon.
The first weeks theme
was Photo-ID. That were also the first days on our research boat Nanuuq. That
time we spend with Dr. Simon Elwen and learnt a lot how to take the best
pictures of dorsal fins on the boat and how to identify the different
individuals. With that data it is possible to get an abundance estimate for the
bottlenose population in Walvis Bay. Bridget showed us later in the internship
how to do that in R and Mark.
The second week was all about behavior. We did a scan sampling on the
boat with the dolphins but also practiced some other methods on shore with
flamingos. Unfortunately we did not have the opportunity to pay as much
attention to that topic as to the first weeks theme.
For the fourth week Dr. Tess Gridley came up to Namibia to teach us
about acoustics. She gave us a little task were we had different signature
whistles and we had to categorize them. The second day we started to get
familiar with the software Raven and became a sound file with whistles where we
had to get some measurements like highest/lowest frequency, time and peak power. The fifth week was all about strandings. We did a strandings survey
along the beach where each of us was allowed to practice some sand driving.
Furthermore we prepared a debate for and against human impact on strandings.
This internship really
helps you to understand how a field research is conducted. Although you do not
have the time to get into every detail as deep as you would like, everyone on
this project was keen to help us understand the different techniques, show us
specifically what we were interested in and of course also how to have a good
time in Namibia.
