maps - Geographic location of Grand (Big) Traverse Bay (red to green contours) along the eastern shoreline of the Keweenaw Peninsula. On the Peninsula, early copper mines are indicated by black dots within the Portage Lake Volcanic Series (dashed lines) and large stamp mills by stars. Two mills (Wolverine and Mohawk) are located near Gay. Insert shows anthropogenic copper inventory “halo” around the Peninsula, in µg/cm² copper

maps - Grand (Big) Traverse Bay: 2010 LiDAR DEM (digital elevation model) colour-coded by elevation and water depth (depth scale to right). Red horizontal contour lines are at 5 m depth intervals. Gay tailings pile (“original pile”) is indicated, as well as migrating underwater stamp sand bars dropping into an ancient river channel (the Trough; at locations #1, and #5). On the eastern flanks of Buffalo Reef, stamp sands are moving out of the Trough into cobble/boulder fields (#3, #4). Along the western edges, stamp sands have migrated as a beach deposit to the Traverse River Seawall (#8) and are slipping down into an underwater depression (#7) next to cobble/boulder fields. Stamp sands are also moving around the harbour outlet (#8). Hence, both the eastern and western sides of Buffalo Reef are experiencing tailings encroachment. Lower on the reef (#2, #6), there is little contamination. Past the Traverse River, the sands in the southern bay are almost exclusively natural quartz grains (#9), forming a white beach with shoreline cusp-like features and bar, plus ridges (#10) of natural sand moving from the shelf into deeper waters off the bay and into Lake Superior

aerial images - UAS high-resolution drone elevation and bathymetry surveys (base map 9 August 2022) of shoreline retreat at the original Gay pile location after bluff removal. Overlays along the beach edge trace shorelines in 2009, 2016, and 2022. The 78 m retreat over 6 years (2016–2022); equates to a 13 m/yr rate. The previous, nearly constant, long-term retreat rate prior to 2009 averaged 7.9 m/yr (ca. 26′) [7,57]. The original Jacobsville Sandstone shoreline, before stamp sands were discharged, is marked by the red border in the far-left upper region. Note white concrete basements of the two mills and remnants of both wooden and broken concrete launders in the northern region. Environmental recovery is beginning, as benthic organisms and fish are returning to clear underwater stretches of the bedrock shelf, where waves have removed stamp sands. Scattered trees (many birch) are beginning to colonise what is left of the original Gay Pile surface.

(b) Photo of 6–8 m high stamp sand bluffs in July 2008 off Gay, showing a buried small lateral sluiceway protruding out of the pile along the shoreline. Lake Superior waters are to the right; the dark beach sands are stamp sands with intermixed slime clay layers. (c) Bluff photo from about the same location in 2019, when shoreline erosion (ca. 7–8 m/year) reached the buried launder support beams, just before bluff removal.

Der Blick der Persom wirkt irgendwie unentspannt. Darüber die Namen der Bands und das Datum, sowie Start und Ort des Konzerts. Die Haare des Kopfes gehen über in eine Art Geäst. Die Farben sind in lila-blau Tönen gehalten. Die Schrift ist in gelb und das Geäst schwarz.

Evolution of #DeepSea Anglerfish Illuminated https://today.ucsd.edu/story/evolution-of-deep-sea-anglerfish-illuminated-in-new-study

Reduced evolutionary constraint accompanies ongoing radiation in deep-sea #anglerfishes https://www.nature.com/articles/s41559-024-02586-3

"deep-sea #pelagic #anglerfishes evolved from a #benthic ancestor and quickly underwent rapid diversification... these results demonstrate that spectacular evolutionary radiations can unfold even within environments with few ecological resources and demanding physiological challenges."

A look back at my 1st paper in 2021, when my 1st PhD chapter was out, on the role of body size and mesohabitats productivities in the linkage of #pelagic & #benthic systems, with David Boukal.

Our study shows that a ‘symmetry in asymmetries’ is critical to maintain multichannel food webs through two compensatory levels of asymmetry that modulate the energy flows in the different food web channels.

Hello to new Blue people! I'm an artist who works a lot with researchers on all sorts of environmental things. Currently artist-in-residence with Convex Seascape Survey looking at #benthic #invertebrates One of my recent pieces made together with refugees and asylum seekers. Called SeaBed. 🧪🦑

Figure 4 in Botrel et al. (2024): "BPP phenology can be monitored by following biological events such as (a) aquatic vegetation flowering or (b) biomass accrual such as periphyton on artificial substrates. These can be visually tracked using (c) time-laps cameras or (d) community science programs, and by using remote sensing techniques including (e) hydroacoustics."

"#neuston did indeed evolve from ancestors that were substrate-attached but not necessarily to the #seafloor. This means that the neustonic organisms may be derived from #benthic organisms and other organisms that aren’t benthic but still attach to a substrates in the #pelagic zone."

An xkcd comic, showing a diagram of a hydrothermal vent. "Chimneys" are labeled, as are "Smoke" above them and "Santas being digested" below.

The text below the diagram reads "Ocean fact: Hydrothermal vent black smokers actually evolved as predatory chimney mimics to feed on benthic Santas."

A conceptualized schematic of terrestrial and marine sediment transport in the tropical coastal system characterized by two sediment transport regimes: one moving marine-derived sediment via hurricane waves and the other terrigenous sediment from the watershed via rainfall.

A difference map of Coral Bay, St. John, USVI. The post-storm November 2017 survey was subtracted from the pre-storm August 2017 survey. Deposition is indicated by positive values (green, yellow, orange, red); erosion in negative values (blue). The largest area of deposition (outlined with a black dashed line) is characterized by deposition ranging from 20 to 60 cm. Coral mounds in central Johnson Bay have a general flute mark pattern of deposition toward Coral Harbor and erosion to seaward. Six sediment cores (white circles) were collected in November of 2017.
