Plenty of things to be grateful for, and plenty to hope

J’en vois qui ne suivent pas. Un bref reminder:

Climate warms. Permafrost (permanently frozen ground) melts. It forms lakes. Organic matter that was previously frozen is released in the bottom of these lakes. Microbes eat that organic matter. It produces methane. Lakes burp out methane. Methane is a greenhouse gas. (Not only arctic lakes emit methane, temperate and tropical lakes do it as well, through different processes).

The question is: what amount of methane is released by lakes all around the arctic, by what type of lakes.

To answer that question, we have two combined methods:

Bubbles traps (plastic skirts) put on high emitted spots on lakes.

Transects (a sweet word to my ears). We do 2 or 3 by studied lake. We shovel a 1x50m on the lake, then splash it with water to have a good visibility. Then we walk along the transect, identify the type of bubble we see, measure them, and GPS them.  Afterwards, to each type of bubble is assigned a mean flux, then the emission values are extrapolated to the whole lake. We also measure ice thickness, water depth, make sediment, gas and water samples..

The goal of the field trip I was in was to have a good idea of lake emissions alomg a North-South transect from Fairbanks to the Kenai Peninsula (South Coast of Alaska, East of Anchorage). We surveyed 13 lakes along this North-South gradient, everytime making transects and samples.

J’ai trouve mon moto.

 

Explication de texte: vous vous souvenez quand je me suis perdue en octobre dans le parc de Denali, pres de Savage River? J’ai fait une carte, la prochaine fois on trouvera la route. Ou pas.

Hi fellows, I’m back! This field trip was awesome. We’ve been really lucky with the weather. I’m still working on defrosting my gear and taking some rest, but after that get ready for loads of cool pictures!

Hi all, I will be in the field from tomorrow until november 22nd. We’ll collect methane emissions from lakes, from Fairbanks to the South Coast of Alaska. We’ll be winter camping, so great pics in perspective. See you soon. Enjoy you warm bed.

‘I heart the Arctic’ est un petit livre illustre inspire de contes et legendes inuits. L’illustratrice Jacqueline Kari a cree ce livre apres un an de travail sur la culture inuits, le graphisme glace de la tundra et les courbes etourdissantes des aurores boreales.  J’aime les dessins, j’aime le sujet. Ca me donne envie de m’y mettre plus serieusement. Je devrais peut etre faire une serie « dans la peau d’un chercheur arctique » ou « la destinee d’une bulle de methane ». Mais je vais commencer par avancer « le petit methane illustre », serie bien reelle sur le changement climatique.
