I am very excited by the recent developments in teaching; it is great that students are invited to disseminate their work on the Internet. Another good example is the blog set-up at the UW for the recent mesocosms experiment performed at the Friday Harbor Laboratory. However, regardless of what the target audience is (potentially very broad for information published on the web), it is a good training for a student to deliver clear messages.

It exemplifies, perhaps, the difficulty in our discussion of ocean acidification, as a simplistic calculation based solely on atmospheric CO2 changes between 1990 and 2012 might lead one to expect a decrease of pH of just over 0.03 (undoubtedly smaller than most laboratories would be capable of observing unambiguously over a 20-year period. Undoubtedly there have been changes in the temporal fluctuations of pH in the Willapa bay region over that period, they are — as yet — poorly documented.

It mentions “In terms of ocean acidification, the results from our study were quite inconclusive. We did not find any significant increase of pH levels as a function of time (1991 to 2012).” It is not clear which results the author is talking about. Also, ocean acidification refers to a decrease rather than an increase in pH. Finally, it is also incorrect to state that research has only been performed at future CO2 levels. Some experiments looked at the effect of past CO2 levels both at geological time scales and during the past decades. Many examples can be found in the ocean acidification blog.

It would be nice if the author could clarify this contribution.

]]> Comment on Sea urchins thrive in acidic oceans by Lina Hansson http://oceanacidification.wordpress.com/2013/04/12/sea-urchins-thrive-in-acidic-oceans/#comment-43760 Fri, 12 Apr 2013 19:53:17 +0000 http://oceanacidification.wordpress.com/?p=12874#comment-43760 Note that the terminology used in this article is misleading. The definition of “acidic” in the Oxford English dictionary is “having the properties of an acid; having a pH of less than 7″. Despite the process of ocean acidification (the acidity of seawater has increased 26% since preindustrial time), the oceans are alkaline (pH higher than 7) and will not become acidic in the foreseeable future. Hence, the words “acid” or “acidic” should not be used when referring to seawater. Note that there are few exceptions, seawater can be acidic in the immediate vicinity of CO2 vents or in purposeful perturbation experiments.
