Filamentous algaes as an indicator of poor environmental status - If the density of think, threadlike algaes cover more than 25 % of rocks, kelp, bladderwrack or eel-grass, we say theu make a problem. More nutrient water with lower Ph (due to CO2), higher temperature, lower saltinity (more rain and more fresh water along the coastline) make the conditions better. 15 years ago the areas in the photos were quite clean from these algaes and filled with kelp and bladderwrack. The same growth is coming along the whole nothern european coastline up to Lofoten. This is from the southern and south-western parts of Norway where the situation is worse than in the North.

Nice and stable film. I'd like to go back some day

Nice posing with a good and clean background. Are there several anemones on this one? It seems to me like it's four or five? Lovely shot.

Avcter the last sad stories, I'll bring some good. This spring / summer has been extraordinary dry with very little floods and little mud, clay and pollution coming into our local fjord. As soon as the conditions are getting better, the marine life is starting to restore, wich means it is hope for the ocean if we just treat it a bit better. Her we see sea squirt (the oceans own cleaning station) covering large aras, sugar kelp growig on previous bare areas, anemones coming back on hte rock and my buddy locking trough an old car wreck with lots of life. The sad part is that it always dissapear after periods with bad conditions.

Here Is the same spot (photo 2 is 3 m. south of photo 1) in 2011 and 2025. All vegetation and.fauna is gone. Both photos are shot in the beginning of march.

Beautiful film with lots of great scenes. It made want to go a place I have not seen before :) . As I do not know anything about the environment and rules in the area (I almost only dive in polar areas) my suggestions might be stupid, but i write them anyway :) In some of the close up scenes, I'd like to see even more stable film. A use of tripod (might be harmful or illegal in some environments) could increase the feeling of the small stuff movoing nearby. The angle of view in the beginning is quite low and, for me, quite perfect. I think I'd like to see more from the same point of view (eg. lower). In the middle of the film, you're back to the sweet point of view. Anyway, it is a lovely film. Thanks for sharing. The lighting is really sweet.

There is an area in the sea near my house called the "Sperm Bank". With such a name, someone had to make a film out of it. We won the fiction category in the Norwagian amateur film championship and got i accepted at the Huston Underwater Film Festival.

In 2011(untill 2016) we had a wall filled with anemones (Metridium senile). During periods of cold and dry weather, we observe an increase in anemones ( photo 2022) . However, they disappear again after the next period of wet weather. Photos - Same spot March 2011, March 2022 & March 2025

I've worked a bit more on my documentation of the sea off Oslo, Norway. Here is the development of a bank of blue mussles in Drøbak. At photo 1 you can see too many common starfish eating the shells. The absence of largert cod (probably due to overfishing) has removed their main predator and photo 2 & 3 show the area in 2022 & 2025. All shells in photo 2025 are empty (eaten by starfish (Asterias rubens))

Here is my photo @Davide DB mentioned in the start of this thread. In the sea near Oslo, I noticed that i the years after 2013, the marine life dissapeared, the water got darker and the sea floor was covered with sludge. The environment was changing much faster than I thought was possible. In the years to 2012, we had sea ice every winter, which is something I have not seen the last ten years. Before 2012, we were normally preparef for 2 - 0 C watertemperature, while it nowdays seldom get lower than 6C during the winter. Frequent floods, underdimentioned water purification plants and high water temperatures during winter time did something with my local sea and one of the effects is shown in this photo. There are similar problems in th ewhole coastline of Norway, but the impact is lower further north. During this winter, I have several spots to document and compare with images shot at the same spot and date from 2008 - 2013.

Hi. I'm Rune Edvin Haldorsen, an underwater photographer, statistican and bass player from Norway. I prefer photographing marine life in the kelp forests of Norway, but later years my main theme has been in documenting environmental effects of high winter temperatures in the ocean, too much fresh water and sludge and plastic pollution. I am not workin as a professional photographer, but still a few of my photos and film has been presented by National Geographic, BBC, Bloomberg, guardian ++ and i had photos on exibition in the UN Climate Change Conference in Glasgow 2021. The added image show some of the documentaiotn i do nowdays. It shows the change in the sea floor at one spot from march 2013 to october 2022. (Same spot, but the upper one shot with 15 mm fisheye and the lowe one with canon 14 mm L MK2)

Hi, Kate. Nice to see you here .)
