Not sure. I don't know a good place to look at archived SLP maps, and discovered this low while looking through EOSDIS archives.
Coincidentally I was looking at
this thing I created back in 2014 or 2015, but didn't continue because it was too much work. I'm considering whether I should do a better, simpler version, as I want to get rid of the Webcams page on the ASIG.
The cyclone shows up between June 19th-24th. Doesn't look too remarkable. If it didn't go below 980 hPa, I can understand why it was un-remarked, although I'm pretty sure there's someone back then who remarked it and commented on it somewhere.
The cloud signature only had an obvious cyclone for a day or two, but there was a period of closer to a week that was cloudy. I'd guess a short lived cyclone of moderate intensity maybe near 980. A track of weakened ice from Laptev through to Beaufort is clearly visible on EOSDIS shots after its passage and from memory corresponds reasonably well to the systems location.
Okay, so I checked the ASIB archive, and what do you know, there was a guy called Neven who wrote this in
ASI update 5:
"It looks like we're going to see the exact opposite conditions in the coming week, with that low staying put over the Beaufort Sea and bringing the Beaufort Gyre to a halt. According to melting-season-rules this should slow down SIE and SIA decreases considerably, but at the same time I can't help but wonder what those cyclonic winds are going to do the ice pack."
In the update conclusion I wrote:
"The question now is: Will the conditions that were so conducive to melting have an inertia-like effect on the SIE and SIA numbers? And what is that big low going to do? Will it tear up the ice pack so we get to see the holes we did in the 2010 melting season?"
The answers were posted in ASI update 6, on July 1st 2012:
"As expected the speedy decrease slowed down considerably, but enough was going on all around the Arctic for the 2012 SIE and SIA trend lines to stay close to the bottom years.
That big low-pressure system definitely left a mark all over the Arctic, see for instance the holes in the ice pack on this satellite image for June 26th. It is very reminiscent of 2010, but earlier this time around."
And after that a big high took over again. So, high, low, high.
In contrast an un-remarked cyclone in 2012 was able to cause dramatic scattering of ice in a large swath from Laptev through to Beaufort.
Un-remarked cyclone? Tsk tsk, Michael. Tsk tsk.
