こんにちは。あきおです。
最近は一年中ハンマーも見ることが出来ている神子元ですが、やっぱりそのベストシーズンは夏。
どこの海にもシーズンがあり一番良い時という物があります。
その究極と言っても過言では無いのでしょうか？
シーズンはわずかに1ヶ月。北海殿の世界遺産知床！
そんな知床でダイビングの限界！流氷ダイビングにチャレンジしてきました。
寒く無いのですか？
もちろん寒いです。2月の知床の平均気温-6.5度。
水温は-1度〜-2度。
寒く無いわけがないのです。
しかしそこにはそんな寒さなんてぶっ飛ばすような出来事で溢れています。
美味しい食事！
かわいいキツネ、鹿、オオワシなどの動物との出会い。
豊かな自然が織りなす風景。
そして季節限定の流氷。
さらに限られたダイバーにしか味わえない流氷の下を潜るエキサイティングなダイビング。
寒さなんてぶっ飛ぶ流氷ダイビングの魅力はたくさんありますが何と言っても水中から見る大きな氷の塊。
絶景としか言いようがありません。
その他にも淡水と海水の境目にできるハロクライン。
このな極限の環境下でも生き抜いている動植物。
その壮大な光景は言うまでもなく、その究極の環境下では不思議な光景がたくさん広がっていました。
それは水中でコンブの先端だけが凍っている不思議な現象や水面近くに浮いている流氷にある空洞。
確かに寒いけどドライスーツをはじめ適切な装備で潜れば寒くはないですよ。
もちろん気温も大きく左右し天気が悪く寒い日だとなかなか体も温まりにくかったりもしますしね。
まぁ僕が潜ったこの日は知床の2月の観測史上最高気温を叩き出した日。
そんな僕に言われても説得力はないか。
Hello. This is Akio.
Recently, we can see hammers all year round in Mikomoto, but the best season is summer.
Every ocean has a season and there is a best time.
It would not be an exaggeration to say that this is the ultimate season.
The season lasts only one month. Shiretoko is a World Heritage site in the North Sea!
The limit of diving in Shiretoko! I have challenged drift ice diving.
Isn’t it cold?
Of course it is cold, the average temperature in Shiretoko in February is -6.5 degrees Celsius.
The water temperature is -1 to -2 degrees Celsius.
How could it not be cold?
However, there are many things happening in Shiretoko that make you forget about the cold.
Delicious meals!
Encounters with cute foxes, deer, Steller’s sea eagles, and other animals.
The scenery of the rich nature.
And seasonal drift ice.
And the excitement of diving under the ice floes that only a limited number of divers can experience.
There are many attractions of ice floe diving that will make you forget about the cold, but the best thing about it is the huge mass of ice seen from the water.
The view from the water is nothing short of spectacular.
The halocline that forms at the boundary between fresh water and sea water is another attraction.
Animals and plants survive in this extreme environment.
Needless to say, the spectacular scene was spectacular, but there were also many strange sights spread out under that ultimate environment.
These include the mysterious phenomenon of kelp tips freezing in the water and cavities in floating ice floes near the water’s surface.
It is certainly cold, but not too cold if you dive with the proper equipment, including a dry suit.
Of course, the temperature also has a big influence, and if the weather is bad and it is cold, it is hard to get warm.
Well, the day I dived was the hottest day ever recorded in February in Shiretoko.
I guess I am not that persuasive.
