Oil spill is yet another issue which has been threatening various oceans of the world. While oil spills triggered by human error have been common over the last few years, the instances of natural oil seeps in certain parts of the ocean have also become quite frequent. Some instances of oil spills triggered by human error over the last year include Deepwater Horizon oil spill, Mumbai oil spill, Barataria Bay oil spill, etc. The best example of natural oil seep, on the other hand, is the Gulf of Mexico oil seep.

These were some of the most prominent events that have been occurring in the oceans over the last few years. Other than the above mentioned oceanography current events, extinctions of marine species, expeditions by various countries, are some of the prominent events which deserve a mention. The vast expanse of ocean biomes makes it difficult to keep a track of all the events that take place in them. That being said, the chances of we missing on some important events that took place in these oceans cannot be ignored. At the end of the day, we can take these events as signs of the problems we are likely to face in the future and put in some efforts in order to make sure that we don't contribute to the damage that is being induced upon the marine life.
