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.

schematic / flow chart - Schematic showing the Bedmp3 source datasets (white boxes) combining to make intermediate products (blue boxes) and ultimately the final set of grids (orange boxes) and their uncertainties (yellow boxes). Note that the surface grid has a uniform estimated uncertainty (Section Uncertainty estimates).

maps - Bedmap3 grids of (a) bed topography and (b) surface elevation, in metres above sea level (g104c geoid), and (c) ice thickness in metres. Locations labelled in (b) are referred to in the text

The BedMachine v3 bed has some subjective advantages over Bedmap3 where glacier flow is relatively fast, but survey data are sparse. (a) Surface flow speed43; (b) BedMachine v3 bed topography; (c) Bedmap3 bed topography, both overlaid on shaded relief and with survey data shown as grey lines. The black dotted line highlights a trough under slow-flowing ice that is more smoothly continuous in Bedmap3. The white oval highlights the trough of a relatively fast-flowing ice stream that in BedMachine v3 is more smoothly streamlined and subjectively more realistic than in Bedmap3, given the typical streamlined form of deglaciated ice stream landscapes. An objective test of bed accuracy in this area requires more survey data.

maps - The Bedmap3 survey dataset allows us to calibrate the more continuous and extensive freeboard-based ice shelf thickness grid. (a) Pointwise ice thickness biases between 119,000 survey measurements and the freeboard-derived ice thickness grid47 on the Ross Ice Shelf, showing coherent patterns of bias; (b) these pointwise offsets median-filtered over a 20 km radius; (c) spline-interpolated calibration grid of the filtered offsets in (b); (d) bias-corrected version of the freeboard-derived ice thickness grid after subtraction of the calibration grid in (c).

“ • A survey of Lake Michigan located at least 40 large craters on the lakebed.
• Initial studies highlighted the spots as unknown shapes, but additional research revealed the craters are filled with marine life.
• Researchers expect to investigate further, seeing how these craters formed and if they’re really sinkholes…"

A sonar image of a few of the sinkholes found at the bottom of Lake Michigan. Earlier this month, scientists with the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory confirmed that circular depressions discovered in 2022 were in fact sinkholes. More than 40 have been found roughly 14 miles southeast of Sheboygan in the Wisconsin Shipwreck Coast National Marine Sanctuary.

A diver investigates the purple-colored cyanobacterial mats at the bottom of Lake Huron's Middle Island sinkhole. Discovered in 2010, Lake Huron's sinkholes have been a hotbed for research ever since.

Purple-hued cyanobacterial mats cover much of the bottom of Lake Huron's Middle Island sinkhole. Discovered in 2010, Lake Huron's sinkholes have been a hotbed for research ever since. The finger-like forms are caused by gases bubbling up underneath the mat.

Researchers from the National Oceanic and Atmospheric Administration Great Lakes Environmental Research Laboratory prepare to deploy a remotely operated vehicle to explore the newly discovered sinkholes in the Wisconsin Shipwreck Coast National Marine Sanctuary. More than 40 sinkholes were discovered 14 miles southeast of Sheboygan in the sanctuary.

Bathymetric map of offshore northern California reveals seafloor features and submarine canyons. (2020)

A multibeam bathymetric survey that produced unprecedented high resolution images of the mouth of San Francisco Bay was conducted in 2004 and 2005. The survey, performed over forty-four days by the Seafloor Mapping Lab at California State University, Monterey Bay, consisted of 1,138 track lines, 1.1 billion soundings, and covered an area of 154 km2 (60 mi2). The goals of this survey were to analyze sediment transport pathways at the mouth of San Francisco Bay and to calculate bathymetric change since the last survey was completed in 1956. The survey showed that significant bathymetric changes have occurred over the past 50 years. (~2006)

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.
