Waking up to the sound of the waves crashing, the wind rustling through the trees are the best sounds to wake up to.
This is the second year the Bhejane Nkonkoni group have been privileged to be assisting in the Mammal Research Institute with their whale monitoring in Cape Vidal. The aim of this research project is to track the Humpback Whales on their migratory paths from their cold feeding grounds in Antarctica to their breeding grounds up north in warmer tropical waters.
The walk to the whale watching towers definitely gets your heart pumping as it is a steep walk through dense forest, soft sand and torturous stairs. But all of that is worth it because once you get to the towers and see the most incredible view out over the sea through the canopy of the trees you forget about the walk up and how out of breath you are.
Stepping up into the towers and seeing the view is like seeing it for the first time every time no matter how many times you go up into the towers.
If you are doing the first shift of the day you have the pleasure of carrying up the theodolite to the towers which weighs about 10kg. You have to set up the tripod legs, mount the theodolite to the tripod and make it level. Once you have set all that up you are ready to track whales moving past.
The main keys when spotting a whale are blows, breaching, fluking and lobtailing. If you spot anyone of these you pin point the whale in the cross hairs of the theodolite and call time. Once time has been called you read off the horizontal and vertical reading to the person scribing and they plot all that data down on a map. To make all the readings on that group more accurate we try to get five readings on each group with five-minute intervals between each reading before the group moves past.
On a clear day with perfect conditions you can see further than 15km out to sea. From that distance you can see these whales breaching out of the water with the naked eye. Sometimes if you are lucky, they will breach really close to the shore and that’s when you can see how big and strong, they are because they literally launch their whole body out of the water over and over again.
The best thing to do between shifts is to go down to the beach either to swim or to explore the shoreline.
One of the best memories I have from last years whale monitoring was seeing a mother and calf humpback whale swimming past the towers just beyond the breakers. This calf was still a new-born because it was so small and you could see that it was still testing out the waters.
As the last shift draws to an end it is time to start packing up the theodolite and all the data sheets from a bust day’s work. Before we head down, we take about five minutes to enjoy the sun getting ready to go down behind us over the dunes while enjoying the final view over the sea for the day.
Then it is time to face the stairs back down to where the bakkie is parked waiting to take us back home for the night only to start this all again tomorrow.
