Temp, Age movies

[PaulSpence]

Create movies of temp and bottom age anomalies on the shelf over first few years.

[julia-neme]

Some animations for the first 5 years of the experiment. They are all monthly anomalies with respect to CONTROL.

Bottom temperature

btemp-monthly-5year-h264.mp4

Bottom salinity

bsalt-monthly-5year-h264.mp4

Bottom age

bage-monthly-5year-h264.mp4

[AndyHoggANU]

For some reason, I can't view these animations. Anyone else in the same boat?

[adele-morrison]

I can see them if I go to the Issue.

[AndyHoggANU]

Nope, doesn't help. Maybe it is because you are the owner ??

[StephenGriffies]

I see upside down smiley faces... Must be an ownership issue.

[adele-morrison]

I think it's a browser compatibility issue. I can see them in chrome, but not safari and not on my phone.

[julia-neme]

I've edited to make the encoding h264, can you check if you are able to see them now? Otherwise, just to test, maybe .gif format is better? Although you won't be able to pause and go forward or back.

Yep, as @adele157 said, I can see the original videos using Chrome but not Firefox. Thanks also to @julia-neme for the gifs, which work in Firefox.

[StephenGriffies]

Amazing videos. Love the coastal fjord signals.

Lovely temp signal very close to the coast especially on the narrow shelf regions to west of Ross moving towards Weddell. Must be advection?

Is the cool region to the west of the Ross in the UP expt one of the katabatic wind spots where bottom water forms?

Bottom salinity signal is more diffuse than temp; quite the opposite what we see in surface anomalies.

Can we explain the two regions of young age (up and downstream of Ross) in the UP experiment via katabatic wind changes?

[AndyHoggANU]

Thanks Julia -- yep, I can see these now.
I agree, it is weird that salinity is diffuse while temperature anomalies are confined to the fjords. Also, the temperature anomaly isn't symmetric with respect to the perturbation -- DOWN acts to warm bottom temperature, while UP initially cools in many places, then later on warms in most places. This doesn't seem to me to be a straightforward response ...

[StephenGriffies]

Yes. For example, the western side of the peninsula is mostly warming in both, though more muted in the UP.

@StephenGriffies regarding "Is the cool region to the west of the Ross in the UP expt one of the katabatic wind spots where bottom water forms?"

No, I've circled the Adelie bottom water region here:

[StephenGriffies]

So is that consistent with not seeing much changes in overall ventilation when cut off the katabatic winds? Namely, the katabatics do not seem to be locally affecting bottom water formation. Do you agree?

[matthew-england-unsw]

I see it more as the katabatic winds not being the limiting factor setting the changes here. So in the experiment where they remain unchanged locally, DSW formation is still affected by the shelf winds being amplified elsewhere.
