In my last post I talked about an intergenerational reading experience. The day after that occurred, I had an intergenerational science experience when I attended the 12th Annual State of Wellfleet Harbor Conference.

The Harbor conference is always interesting, moving smoothly between very local issues in Wellfleet Harbor to regional issues in Cape Cod and New England, and on to global issues, especially those related to human activity, such as global warming, sea level rise, pollution, and decreasing biodiversity.

The presentations and posters dealt with a wide variety of topics: river herring spawning migration, including transponder tracking, training robots to assess landscape change in the Herring River floodplain, shellfish for nitrogen mitigation, horseshoe crab conservation, modeling sea level rise and vegetation change, ocean sunfish strandings, eel monitoring, restoring the Mayo Creek salt marshes, diamondback terrapin nesting, among others.

Although the sessions were diverse, there was a common theme of restoration, going from “How can we assess the damage?” to “How bad will it get?” to “Is there anything that can be done?” It was depressing to see the many ways that we’ve destroyed a beautiful habitat, even one that is supposedly protected by the National Seashore. On the other hand the efforts at restoration are impressive and may at least provide information about what not to do in the future. There was discussion of plans to restore Herring River and Mayo Creek, salt marshes, and many individual species of sea life. If these restoration projects are to succeed they need to involve a large public of all ages, not just a few scientists.

The conference was a delight to attend, even more so since most of the topics related to areas easily accessible by walking or paddling from our home. For example, we’ve seen the amazing ocean sunfish stranded on Mayo Beach only ten walking minutes from home and friends have encountered live ones while kayaking just offshore.

Aside from presenting an opportunity to learn about many topics, the conference was another good example of an intergenerational experience. Presenters included college students and volunteers of all ages. The audience was diverse as well, with some who remember well times long before the National Seashore was created.

One of the presentations was by Nauset Regional High about their own research in collaboration with the Wellfleet and Truro fifth grades. It was the first time to have K-12 presenters at the conference. The students wanted to compare oyster growth and mortality in Herring River and Mayo Creek. An interesting question for their study is that the streams experience tidal variation and high salinity at their outlets, but vary to mostly fresh water higher up: Would oysters be able to survive and thrive away from the sea? Each group of students measured and marked a set of ten oysters. There were five bags for different locations on the Herring River and three for Mayo Creek. The young scientists left each bag with oysters for six weeks, then collected it and re-measured the oysters.

The students learned some of the challenges of field science. For example, one of the oyster bags was missing when they went back to collect it. Valerie Bell, the environmental science teacher at the high school, asked the audience almost as a joke, “if you come across a bag like this can you give us a call?” To my amazement, someone in the back called out that they had in fact found the bag. It must have broken from its mooring and floated with the tide to another location. It was a small thing, but a nice example of community science in action.
