A quick introduction.
Professionally, I wear multiple hats. I'm an aquatic #biogeochemist that focuses on #nutrient cycling in aquatic ecosystems. I also dive into #hydrology to understand how water moves. I enjoy statistics and love #rstats (sometimes😉)

1) With the plethora of data and more being collected with longer-term studies/analyses being developed, sampling frequency and data inventories are becoming more and more important to understand not only how the system has changed but how the monitoring has changed.

Have you ever looked at a complex model and wondered what variables explain the most variance, an idea from colleagues who live in the multiple linear regression world. Not sure if I did it right for GAMs, so I posted the question with reproducible code ...

It's like if you mentor somebody and invest time you benefit ... Strange 🤔
Yes, that was sarcasm. Accepting a student (as a graduate student) is an investment in the future and your legacy. It should be taken seriously.

What makes PhD students happy? Good supervision
Supervisors who invest in positive mentoring relationships with their PhD candidates also reap the benefits for their own research.

I've been listening to a lot of @classicfm.com lately, it makes me feel like I'm listening to a little box radio, sitting next to a fireplace in a comfy chair, sipping tea in some cottage in the Cotswolds or Lakes District.
... close, just 5000 km away. But still got the fireplace and comfy chair

Probably the last good weekend to catch the autumn colors, albeit muted due to the drought. As expected, there was a water/limnological based theme 😉. We visited ESF Pond 1 in Heiberg Memorial Forest, Clark Reservation State Park, Chittenango Falls State Park, and Nelson Swamp unique area (no pic).

Looking at the titles of manuscripts from the past is fun ... it seems much more relaxed. Like this one "Sveriges geologiska undersöknings torvinventering och några av dess hittills vunna resultat." roughly translated to "Sweden's peatlands geological survey and some results gained so far."

I was reading a paper today about stable states ... and they have ASS throughout the paper as an acronym for Alternative Stable States. In the associated code, they have a data.frame where they combined two very large datasets and called it bigass ... couldn't stop laughing whilst reading the paper.

Checked out Lake #George for #WorldLakeDay 🌊 Just 60 mi from Lake #Champlain, but water levels tell a different story: while trending down its not as drastic as Champlain 📉

Following up on Lake Champlain levels: USGS data show major tributaries (Saranac, Ausable, Boquet, Lamoille, Winooski, Otter) are at record-low summer flows. Most <5th percentile. Drought or shifting climate? 🌦️🌊 #fedopendata

Lake Champlain is at its lowest for this time of year in over 50 years, much earlier than it should be.
To visualize this, I created a calendar plot that bins 50 years of lake stage data into quantiles.

Every summer, algae blooms erupt across Florida’s largest lake, choking the ecosystem and threatening our economy.
We collaborated with the National Park Service using decades of ecosystem monitoring data to develop a predictive algae model.

A beautiful blooming Columbine (Aquilegia app). Not the native but excited to see its beautiful bloom. We will still be planting the native and slowly transitioning this area to native dominate. Plus we don't want to completely rip out everything the prior owner loving cared for.

On our evening walk last night we came across this plant. We've been trying to ID it but the closest we've come is Sorbus americana (American Mountain Ash). The American cousin to the European Mountain Ash ... as in Rowan trees!! 🤞🤞 We're right, I would love to have a native "Rowan".

If you know me, you know that I love to garden. I especially love planting and growing plants. While I grow fruit & veg, I'm more of an ecological gardener, a gardener for wildlife rather than a showy & pretty garden. Granted, you can garden for wildlife & make it look pretty.
