This information will help us to identify and protect critical whale feeding and breeding areas. Over coming years we will try to raise awareness of the need for blue whale conservation at the national and regional levels, and secure protection through Marine Protected Areas MPAs. In , three protected areas covering , hectares were approved by the Chilean Government.Whales are an important part of the marine food chain and play a huge role in maintaining the health of our oceans.While it may be considered an endangered species, the blue whale is truly international, occurring in all oceans except the Arctic, and enclosed seas of course. Before whaling there may have been as many as ,; today, it is one of the world's rarest species, with the population of blue whales numbering just 10,, Most biologists consider it among the most endangered of the great whales. Only one population, in the northeast Pacific off California, is showing real signs of recovery and it contains around 3, animals.Their iron-rich poo is a really important source of nutrients in the marine food chain, promoting Southern Ocean productivity, which boosts fishery yields. These nutrients, particularly iron and nitrogen, are vital for phytoplankton, at the base of the food chain. Because plankton help to remove carbon dioxide from the atmosphere, you could go as far as to say that blue whales are carbon neutral.However you calculate it, whales are fertiliing their feeding grounds and providing sufficient nutrients to sustain krill populations. Although there is debate surrounding the taxonomy of blue whales, there are five distinct subspecies: Antarctic blue whales in the Southern Ocean Balaenoptera musculus intermedia ; North Atlantic and North Pacific blue whales Balaenoptera musculus musculus ; Pygmy blue whales, found in the Southern Indian Ocean Balaenoptera musculus brevicauda ; Northern Indian Ocean Balaenoptera musculus indica and South Pacific Ocean Balaenoptera musculus unnamed species whales.Climate change, ship strikes and entanglement in fishing gear are the primary threats faced by blue whales. Additional threats that could potentially affect whale populations include anthropogenic noise, habitat degradation, pollution and vessel disturbance. Noise pollution Blue whales use sound to find their partners and perhaps location of topographic features and prey. Man-made noise can potentially mask their vocalisations, throwing them off-course and disrupting both movements and breeding.Potential sources of man-made underwater noise in Australian waters include seismic surveys for oil, gas and geophysical exploration; industrial development such as drilling, pile-driving, blasting and dredging ; gas processing and shipping. Increased shipping traffic Vessels can collide with whales or disrupt their behaviour. For millions of years, whales have cruised the world's oceans with hardly a care, their sheer size leaving them largely free from danger.

      How Many Days in Oslo you might ask, and the answer depends on whether your priority is to enjoy the beauty of Norway. If that is the case, Oslo is just a starting point and the likely city from which you leave Norway. Many travelers want to hike in its pristine landscapes or see the Northern Lights rather than see what Oslo has to offer. In my case, I was interested in Oslo itself, and its immediate hinterland.From my research, I realized that Oslo was a very underrated capital city. My visit over just a weekend confirmed that. Oslo is steeped in history , is known for its great cuisine and offers a relaxed atmosphere for all visitors. Its population is in excess of , but with so many open spaces, I never felt that I was in a large city. I hoped that I could get to know Oslo fairly well in 2 days.There was never going to be too much time to travel further afield The Oslo Pass with so many benefits seemed to be good value. I would certainly recommend it to every traveler. Sentrum is one of the best areas to stay in Oslo for tourists because it is central with quick and easy access to famous attractions and landmarks, and public transport enabling easy travel to other regions of the city.Aker Brygge is also a great choice for tourists as it offers a great selection of dining options, bars and cultural activities such as galleries, on top of beautiful architecture and interesting walking routes. I was happy to start early each day in order to see as much as I could of Oslo. In just one day, you can walk along the historical wharf and grab some photos of the famous wooden houses. For those looking for some Winter Olympic history, a 2. Delve into the Lillehammer Winter Olympic history with a visit to the exciting and modern Olympic museum.Staying a few days there? How many days is enough in Norway? Olden is a quiet village situated at the mouth of the River Oldeelva and sits at the end of the mile Nordfjord.This pretty little village is renowned for its Norwegian hospitality, natural beauty, and the many wonderful things to do. The winding, peaceful valleys meet colossal glaciers and crashing waterfalls, all set against the beautiful backdrop of towering mountains.Reset your mind and kayak out onto the peaceful glacial lakes , or explore the Norwegian wilderness and take a trip guided by locals up into the deserted mountains and enjoy some local cuisine! Another recommendation of ours is to venture further north still and explore Alesund.This famous road snakes its way through 11 steep hairpin bends to a casual metres above sea level. The drive squeezes endless jagged mountain peaks, glacial mirror-like fjords and cascading waterfalls into it — all ready for the camera!For those lucky enough to have the gift of time on their side, head out to the remote locations and really explore Norway. The Lofoten Islands , an archipelago off the coast of mainland Norway, are absolutely breathtaking and famous for their dramatic scenery. With activities ranging from hiking to skiing to surfing and colourful fishing villages at every turn, you may want to consider moving there permanently!Wondering how to get there? Numerous airports throughout Norway have flights out to the islands, but the most exciting way is to hit the high seas and take the ferry. We recommend spending 3 days on these unique islands to really appreciate what they have to offer.TripSavvy's editorial guidelines. New York University. Rutgers University.
