New pub alert #AGUPubs! Small, shallow waterbodies are among the most productive freshwater ecosystems on the planet! In this @GLEONetwork #ponding collaboration, we examined ecosystem metabolism in 26 shallow waterbodies in N. America and Europe. https://t.co/cigbRYCD9f

I'm so excited to share some of our new work mapping ponds! PhD student Denghong's remote sensing skills are enviable :) Now he's working on mapping ponds throughout NYS. Stay tuned!

New scalable method to accurately detect small (yet important) water bodies down to 0.1ha with spectral-temporal-spatial features of Sentinel-1/2 data. Check out our fresh #RSE paper https://t.co/Kr8NN1tpCQ with @SheelBansal @pondscience and Xiaolin Zhu's lab at HK PolyU.

Do you have results related to lake mixing to share at the @aslo_org Aquatic Sciences Meeting? Join @pondscience @mindym1101 @LienneSethna and me in "SS07: Ecological impacts of infrequent water column mixing events" Deadline extended to 10/28! https://t.co/DQraVCYsVW

@GLEONetwork Our study provides more evidence that ponds are truly biogeochemical hotspots! This work was such a fun collaboration years in the making. @JoeRabaey @DRichardsonLab @jbcotner @EvoEcoEric and many more not on here!

@GLEONetwork We also explored how well metabolism models (designed for bigger, deeper lakes) work for ponds. Metabolism models work best in sites that are more productive and have bigger diel oxygen swings. Models performed poorly in less productive / more heterotrophic systems (3/4)

[Meredith Holgerson @pondscience]

@GLEONetwork We observed high rates of GPP (mean 8.4 g O2 m-3 d-1) and R (mean 9.1 g O2 m-3 d-1), while NEP varied from net heterotrophic to autotrophic. Metabolism rates were affected by depth and plant cover; the shallowest waterbodies had the highest GPP, R, and most variable NEP.

🚨New pub alert!🗞️Check out our work in @JBiogeochem comparing net denitrification (N-removal) vs. net N-fixation (N-addition) in FL stormwater ponds (SWPs) vs natural undisturbed ponds. Spoiler: SWPs are more often net N-fixing compared to natural ponds

@isabella_oleksy Katie's the best!! We miss her already and are so excited to see what awesome science you do together :)

[Meredith Holgerson @pondscience]

@lewis_lakes Congratulations Abby!

[Meredith Holgerson @pondscience]

@mindym1101 So happy for you! Very well deserved!

[Meredith Holgerson @pondscience]

@AshleyBulseco Hang in there, Ashley! The days are long… the years are short. Sleep does return!! You’ve got this!

@JenniferRaff Since the Children's Museum closed 😭, try OMSI (planetarium; kids section) and zoo. My son used to love riding the MAX (light rail) + trolly (the aerial tram is also cool). Powell's Books has great kids section. Japanese Garden, Forest Park, + nature playground in Westmoreland.

[Meredith Holgerson @pondscience]

@precatlady @burginam @JenniferRaff So sad to hear this. My son loved the PDX children's museum when he was a toddler.

[Meredith Holgerson @pondscience]

@AJ_Heathcote If they place us on Friday afternoon, then yes. If not, TBD 😂

#ASLO24 - We welcome your abstract submissions for our special session on the role of macrophytes in aquatic biogeochemical cycles! Hope to see you in Madison this June.
