Marine carbon dioxide (CO 2 ) removal (mCDR) is an emerging strategy that aims to fight climate change by taking advantage of the carbon capture potential of our oceans. There are multiple types of mCDR approaches being evaluated globally, one of which is ocean alkalinity enhancement (OAE). 
 
 According to NOAA , OAE aims to increase the pH of water by either adding alkaline material to ocean surface waters or by removing acid from seawater. Due to the change in acidity, the chemistry of seawater changes, making it capable of absorbing greater volumes of CO 2 .

Citizen science programs have popped up across the United States, focusing on connecting local communities with nearby water resources and building a trustworthy data pool over the sampling period. While commonly utilized as a means of ensuring that large watersheds or lake regions are adequately sampled, the credibility and success of such programs have been called into question.
