The bar chart illustrates the populations of three different marine mammals—seals, whales, and dolphins—in the Gormez Straits from 2006 to 2018.
Overall, the populations of all these animals increased over the years, with the last year showing the highest statistics for seals, whales, and dolphins.
In 2006, seals were the most populous marine mammals in the Gormez Straits, with a peak population of approximately 43. However, this number fell significantly to nearly 25 by 2010. After this decline, the population sharply rose again, reaching approximately 45 in 2018.
During the same period, whale populations started at just over 20 in 2006 and fluctuated between just over 20 and just below 30 until 2018.
Although the number of dolphins was just over 15 in 2006, this figure clearly increased to nearly 21 by 2010. Following this upward trend, the dolphin population consistently rose to approximately 32 in 2014, before peaking at just over 50 in the last year.
