Podcast’s Essential Bites:

[6:00] BG: “Historically, [tide] data comes from really two types of sources. One are installed tide gauges. And so these are installed on piers or docks or harbors with a fair amount of infrastructure and multiple ways of actually measuring water level or from satellites. And so when you hear things from NASA or from NOAA saying that sea level rise has increased over several millimeters this year […] that's an average that's accumulated globally from satellites. But when you hear that NOAA is predicting a high tide flooding event in three or four weeks from now […] that's coming from more localized sensors.”

[6:56] NE: “Coastal communities rely on tide data for a number of reasons. For example, something as simple as tourism, which is typically the bulk of the economies of many beachfront communities in the US. […] Another way that communities typically rely on tidal data is for things like coastal flooding […]. And the big challenge for the communities to prepare for flooding events […] at the episodic scale, as well as the longer term sea level rise is the spatial coverage of those type sensors […] is so sparse. The federal tide sensors that are available, for example here in South Carolina, they're only 2 or 3 along the entire state coastline.

[24:35] BG: “There are researchers who are using these individual gauges as part of […] climate change research looking at accelerated effects in the coastal zone. There are municipalities, there are city and county sustainability officers, cyber Infrastructure data managers […], individual nonprofits who are engaged in coastal restoration.”

[25:09] NE: “Another interesting partner that we've pulled in on this southeast project is the National Park Service. So they have a lot of infrastructure, national seashores that are at risk along the coast here. Industry, so some of the larger consulting firms are joining and wanting to be able to provide that information to their clients.”

[32:41] BG: “By 2030, the national median high tide flooding events are probably going to increase by 2 to 3 times and 5 to 15 times by 2050. Along the US coastlines alone, there's $120 billion real estate that's at risk of flooding twice a month by 2050. And the communities need access to be able to start to plan for how to approach this, because […] that can't happen at the federal government level, it has to happen from the community level. And the first way to start thinking about planning for mitigation is to actually have local information on the physical environment.”
