Uzoma Edijmadu is a PhD student in Lagos, Nigeria studying manatees in Badegry Lagoon. He uses his new secchi disk to check water clarity, which is important to understand where aquatic plants (manatee salad!) are capable of growing.
The new depth sounders are great because they not only give the depth of the water (very important when searching for manatees in murky rivers and lagoons), but also the water temperature, all with the click of a single button! Bolaji Dunsin of the Nigerian Institute for Oceanography and Marine Research, who collaborates with Uzoma, checks their location on their new GPS while surveying Badegry Lagoon in western Nigeria.
