Notes
Assisted by Matisse
Great data set again - with some really interesting low DO's in the bottom stratified level. This is similar to what we found prior to the last artificial opening and i think this represents some 'old' seawater which has been in residence for some time now. This doesn't pose any risk due to a highly oxygenated profile downstream, but a good example of where winter flushing is required to reset the system! Thanks Jarred.
