Together, the instruments produced 64 data points per second over several days. Combining the massive dataset with an analysis technique that was still a work in progress wasn\u2019t easy, McGinnis said, but it was rewarding.<\/p>\n
\u201cIt was a really neat study, and it\u2019s such a new technique,\u201d McGinnis said. \u201cWhen you get a new dataset, it\u2019s always a little bit challenging to work with.\u201d In the course of working through the data, McGinnis produced a series of software tools that should help other researchers use the eddy correlation technique. They\u2019re available for free on his website.<\/p>\n
\u201cThe most remarkable thing I think we saw was how much the oxygen can change \u2014 the flux,\u201d McGinnis said. \u201cConventionally, people aren\u2019t used to thinking that the oxygen can change that much in a permeable system.<\/p>\n
\u201cWhen we first analyzed the data and finally got the numbers out, I almost couldn\u2019t believe it.\u201d<\/p>\n
McGinnis, now an assistant professor at the University of Geneva, believes that the eddy correlation technique could greatly improve the way scientists study dissolved oxygen flow and other geochemical processes. It shows promise where other methods fail due to terrain, such as clam beds and rocky substrates. In the future, McGinnis plans to continue using the method in rivers and lakes.<\/p>\n
\u201cIt\u2019s a nice method because it can be applied in a lot of areas,\u201d McGinnis said. \u201cIt doesn\u2019t interfere with natural hydrodynamics and light regimes, it\u2019s a really noninvasive method.\u201d<\/p>\n
\u201cHopefully people will use [the landers] as a more routine technology,\u201d he said.<\/p>\n","protected":false},"excerpt":{"rendered":"
