Sending support from the South Puget Sound, where we are also working to restore our native Oyster and Seagrass meadows :) cheers to a future with healthy biodiversity across the globe
Congratulations on receiving funding from the government Also this work about mycorrhizal association in sea grass is amazing I didn't even think that was a thing I wish you the best results (I love the ocean
Congratulagion on the funding you got, you are doing such an interesting job. I look forward to see more about it in the future. I really like the name you choose for the boat.
Thank you. :) We also considered oystercatcher, or trìlleachan (learngaelic.scot/dictionary/index.jsp?abairt=oystercatcher&slang=both&wholeword=false), but it would have been a tricky name to spell phonetically over the radio should we need to! Cheers, Isla.
Hello! Thank you, and good question. We don't yet have a handheld salinity meter, but especially as we're headed into the winter season and rain will be more of a factor we might need to get our hands on one. Interesting side note, when out in the field we often note that common eelgrass (Zostera marina) forms dense patches where low energy freshwater streams come into the intertidal. We're not entirely sure why this is but always note it to other interested seagrassy folk! Hoping our fieldwork will shed more light on this. Cheers, Isla.
Hi, I’ve been thinking about rearing sea grass in a lab environment like you mentioned. I am curious to know if water current is necessary for sea grass to develop roots? Is that something you have planned in the lab rearing or is that unnecessary for successful growth. Thanks!
Hey! Isla here, good question. At the moment we are only constructing tanks, filling them with seawater with a small amount of sediment and seeing if transplanted seagrass plants can survive in that environment. We've also planted seeds in some of the tanks. In a natural setting it is extremely difficult to isolate the factors which may or may not be influencing seagrass growth and survival, so our aim in this artificial setting is to start with the basics (water, sediment and natural light) and progress from there. Because of the early stage we are at we do not yet have information for you regarding water currents and root establishment from our own nursery trials, though I did find a related paper you might find interesting: link.springer.com/article/10.1007/s10980-018-0739-4.
Thank you for the interesting question. Really odd - I had typed up a response to this a week ago but I now see that it is not here so here we go again! We haven't considered water current yet as we're starting with the basics (sediment, natural sunlight and seawater) so that we can determine the factors that are necessary for growth for the seagrass within our project area. It is likely that we will add in new variables when required as we navigate through this process. I'll be sure to mention water current to Francis! In short, no clear answer for you but I did find some relevant literature online on the topic. Pasting a link might be why my previous comment was deleted so I will leave the title: Seagrass-sediment interactions, positive feedbacks and critical thresholds for occurrence: a review. It is likely that there are regional and seasonal variations and different optimal thresholds for variables such as water current according to these variations. Different populations of seagrass can behave differently even within species (such as Zostera marina that has subtidal and intertidal varieties), and each likely have different requirements when grown in an artificial setting. This is part of the joy of rearing seagrass in an artificial setting though - it is far easier to isolate certain variables that might influence seagrass growth and survival rates. Hope this helps. Cheers, Isla. :)

Thank you and good luck with your work! - Cheers, Duarte
Recently moved to the puget sound area! Nice to see ya here neighbor
@@greatgongo3772 hello and welcome to the area freind!!
Thanks for the update. Glad you got some funding. Excellent project.
Congratulations on receiving funding from the government
Also this work about mycorrhizal association in sea grass is amazing
I didn't even think that was a thing

Thank you, the project has really come on leaps and bounds this year! We really appreciate your support. :) Cheers, Isla.
Looking forward to seeing more about the sea grass and oysters!!
There will be one of these updates every month! - Cheers, Duarte

Great video- Ty for the updates!!:D
Glad you enjoyed it! Thank you for the support! - Cheers, Duarte

Love your name choice for the boat.

Loving the project!
I wonder, do you measure the salinity levels in your seagrass nurseries (rain can lower salinity levels), or is that not an issue?
Hello! Thank you, and good question.

That IS interesting! Thanks, and good luck with everything!
