Below are my suggestions (page and line numbers refer to these in the track changes version):
Page 1 line 16: delete ”describe”
Page 1 line 18: delete “more”
Page 1 lines 19-21: “We found that the semi-rigid chambers performed well, and had numerous benefits including reduced gas permeability and optimal stem gas exchange surface to total chamber volume ratio (Sc/Vtot) allowing better headspace mixing”: Personally I do not like the hollow words like “the semi-rigid chambers performed well”, you either delete them or be specific to let the readers know in what way and by what kind of parameters you claimed that the semi-rigid chambers performed well. Similarly I also do not like “numerous benefits”, just directly list the most important advantages. Better just change to “had reduced gas permeability and optimal ratio of stem gas exchange surface to total chamber volume (Sc/Vtot)…”.
Page 2 line 28: “access logistics are”: change to “access logistics is”?
Page 14 Lines 376-378: The rigid chamber was 14.1x larger than the small sleeve and 9.7x larger than the large sleeve, and the initial concentration gradient in the rigid chamber was 14.0x smaller compared to the smaller sleeve and 9.01x compared to the bigger sleeve”: 9.01 x smaller?(line 378). What does “14.1 x larger” really mean? (Please note that mathematically 6 is 3 times of 2, or 2 times larger than 2). Also “14.0x smaller” is somewhat weird. To be accurate, better change the style “14.1 x” in the whole text. For example, “The rigid chamber was 14.1x larger than the small sleeve” can be rewrite as “The rigid chamber was 14.1 times that of the small sleeve in volume”? And “the initial concentration gradient in the rigid chamber was 14.0x smaller compared to the smaller sleeve” can be rewrite as “the initial concentration gradient in the rigid chamber was only 1/14.0 of that in the smaller sleeve”?
