New deep sediment recovery

On 19 September 2022, I went for a new sediment recovery. The goal is to find micrometeorites in these sediments.

This time I decided (or I tried) to make it easier, and funnier. I went using my canoa, directly from the shore next to my home.

The place where I live is extremely windy and the sea is normally wavy with a lot of current. And I like it. But for recovering sediments, this is not helpful. I had to wait for a very calm day. On 19 September 2022, the weather was perfect for this purpose. No wind, no wave. Here, this only happens a few days each year.

The place where I decided to go is: 27.8658 N -15.3604 W.

This is 2.5 km away from an hostil shore, and 3.0 km away from the place where I can put my canoa into the water.

Here is a depth profile of the place.

The depth was about -75m so I could use a kind of enhanced fishing rod with reel, and a container instead of a hook.

This is the picture I took just before I started to recover sediments:

The water conditions can change very fast. There was no much time to take pictures. I took all security measures. I would have come back to the shore immediately if the weather would have shown any minimal change. The mobile phone did not loose connection so I could still make a phone call in case of an emergency. All in all, it was a great experience.

I managed to recover about 2 liters of sediments.

Here is a picture when I come back to the shore:

My first attempt to identify micrometeorites in the sediments, using about half of the sediments, was unsuccessful. But I will check the second half as soon as I can.

And of course I will go back to the sea on the next "window" of safe weather, to recover more sediments.

This is not only finding micrometerites. The path is probably as beautiful as the goal. It would be great to find micrometeorites this way. So I will persevere.
