By Shannon Dunnigan I create most of my data visualizations using R, which for most people seems like such a daunting task. Yes, R certainly has a learning curve, especially if you are not familiar with writing code, but there are so many cool things you can create using it! We have talked about R…

Preparing for presentations
By Shannon Dunnigan and Kaitlyn Dietz Preparing for an upcoming presentation is probably one of the most stressful experiences I have ever had. Not only are you time-restricted in many talks (that evil 12-minute window), but finding the EXACT information that summarizes your research perfectly is incredibly difficult. Currently, I am developing a presentation Pam and…
The visualization of rain
By Shannon Dunnigan I am sure most of you NERRds can agree that the visualization of data is an integral part of the scientific process. In fact, I would further argue that it does not simply occur ONCE, but multiple times throughout the process. Visualization is a key step in detecting patterns and relationships within…
The winds did what?
By Shannon Dunnigan Hey there, it’s been a while… If you did not catch the last few posts where we NERRds have discussed the recent Hurricane Irma, I highly recommend that you check those out! The first was a piece I wrote at the beginning of my investigations into the effects of Irma in the…
Eclipsing the sensor
The following post was written by a guest writer and a true fellow NERRd! Seriously, though, she works at another NERR… Kim Cressman is the Water Quality Monitoring Coordinator for Grand Bay NERR and a part of the SWMPrats team. She has a master’s degree in marine biology from the University of North Carolina Wilmington,…
What’s R?
By Katie Petrinec Let’s recap a little… If you remember from the last post, we left off with editing the historic data files, all files prior to 2007. Using the metadata documents, we recoded all the 2003-2006 data files and added the suspect data flag and appropriate CDMO code to the data file. We then…
Re-Coding Our Data Files
By Katie Petrinec Let me begin with where we left off last… After realizing that our dataset contained turbidity values that exceed 1000 NTUs. We realized that further steps were needed in preparing the data before we could begin any sort of analyses. If we were noticing these patterns in the turbidity data, what about…
Understanding Our Data Files
By Katie Petrinec For the past year, I’ve had the opportunity to really delve into our SWMP data with the goal of providing a 10-year analysis of SWMP data [almost] since the program’s inception at the GTMNERR. Analyses of the SWMP datasets are necessary to identify estuarine impacts of events like hurricanes or prolonged droughts,…
