The graph provides information about the recorded changes on the seal, whale and dolphin population in the Gormez Straits between the year 2006 and 2018 (2006, 2010, 2014 and 2018, respectively). The bar chart divided into 4 sections of timeline.
The first recorded timeline is 2006. In this year it can clearly be seen that the seals’ population had out numbered the whales and dolphins. The dolphin population is close to 20 in 2006. The whale population is slightly higher than 20 and the seal population is nearly twice as much as the whales in 2006. Turning to the year of 2010, there are a significant decrease on seal population to nearly 20. However there were a small increase for the populations of whales and dolphins in the same year.
According to the year 2014, population of both seals and dolphins passed the 30. But the number of whale got closer to 20. And finally when we examine the year 2018, population of all three creatures are increased. Whale population was approximately 30 and the number of seals become more than 40. Furthermore the biggest change can be seen on dolphins’ population, as they increased more than 20 and passed 50.
