He is the founder of the MBAD African Bead Museum in Detroit. Through material culture, Dabls presents commentary on the past, present, and future from African and African-American perspectives, with the understanding that generations of African ancestors used visual materials to convey information about their identity as well as send messages for healing and protection. Dabls is a luminary; for decades he has re-imagined what a museum space can be, accessible to everyone, free from the underpinnings of colonialism and the Western, often white, frame. *Grand Vision* includes a conceptual installation in the Gallery, presenting Dabls\u2019s own work in visual conversation with African beads and artifacts from Dabls\u2019s Bead Museum collections. \n\nAdditionally, Dabls\u2019s iconic outdoor sculpture *Iron Teaching Rocks Table Manners* will be installed on the U-M campus grounds near UMMA, at the intersection of State Street and South University from September 17- October 11, 2026.

The oxygen isotope records from skeletal materials are a key part of the toolkit for studying past climate with extensive use in marine and terrestrial settings including in lakes. For the Laurentide Great Lakes in North America, \u03b418O values (\u03b418Ocarb) of molluscs and ostracods (biogenic carbonates) have helped us understand their formation following the melting of the Laurentide Ice Sheet, subsequent isostatic rebound, and regional climate change over the past 15 ka. Biogenic carbonate \u03b418Ocarb values from Lake Erie, the shallowest of the Laurentide Great Lakes, have been critical for understanding its water balance, which is very sensitive to hydroclimate fluctuations. This works because \u03b418Ocarb values reflect the isotopic composition of lake water (\u03b418Olw), which is very sensitive to changes in lake evaporation or input sources. However, \u03b418Ocarb is a function of multiple hydrologic (temperature, humidity, evaporation, input sources) and isotopic levers (the isotopic composition of lake and atmosphere) which can significantly impact the \u03b418Ocarb value. In this dissertation, I demonstrate the advantages of evaluating the \u03b418Ocarb data in relation to regional water balance, lake configuration, and temperature constraints over the last 15 ka. \n\nChapter 2 characterizes the modern hydrological conditions of Lake Erie by evaluating the seasonal and temporal isotopic (\u03b418Olw, \u03b42Hlw, and \u03b4\u201917Olw) variability of local precipitation, river, and lake water within the lake basin. Our results show a systematic variation in \u03b418Olwr, d-excess and \u039417Owater data of lake waters in relation to seasonal conditions and basin location. I then utilize the well-monitored hydrological system of the Great Lakes to constrain the fraction of moisture from the lake (f) parameter and the ratio of turbulent to diffusive fractionation (phi or n) parameter for Lake Erie. Both parameters are essential to the lake-water isotope mass balance models and significantly affect the isotopic composition of the water (\u03b418Owater) but are poorly constrained. I show initial studies constraints on f and phi are too restricted and I proposed an updated look at the variation in f and phi values.\n\nChapter 3 employs the isotope mass balance framework established in Chapter 2 for paleohydrology reconstructions of Lake Erie. I utilize biogenic carbonates from sediment cores from the eastern and western basin of Lake Erie to reconstruct the isotopic composition of formation water (\u03b418Ofw) in respect to changing lake configurations and temperatures over the last 15ka. This chapter reviews previous assumptions about lake hydrology in relation to input sources, lake evaporation, and basin dynamics and suggests that a water balance modeling approach can be used as an additional measure to constrain lake conditions. I demonstrate with mass balance modeling that Lake Erie was an evaporative lake during from ~15 to 10 ka, contrary to previous interpretations that Lake Erie was a high stand lake. After 10 ka, our mass balance approach supports previous interpretations suggesting that Lake Erie transitioned to a highly evaporative closed basin lake before shifting to its modern hydrology ~5ka. \n\nChapter 4 seeks to utilize micrite samples from the same sediment cores in Chapter 3 to evaluate whether lake micrite can reconstruct regional paleoclimate. Using x-ray diffraction (XRD), scanning electron microscopy (SEM), and clumped isotope geochemistry (\u039447), I analyzed samples for detrital contamination and whether these samples can be used to contextualize regional landscape changes in the Lake Erie basin. I find that all samples from the eastern and central basin have detrital contamination with reconstructed \u039447 temperatures ranging between 45 to 64\u00b0C. No micrite \u039447 temperature matches modern lake temperatures but matches previous Paleozoic and Mesozoic detrital limestone clasts \u039447 temperatures. \n\nThis dissertation represents a more extensive application of water balance modeling for paleoclimate applications and contributes abundant isotopic (\u03b418Olw, \u03b42Hlw, \u03b4\u201917Olw, \u03b418Ocarb, \u03b413Ccarb, and \u039447) data for modern and paleo-lake systems. The data from this dissertation illuminates a strong connection between the water balance of Lake Erie, lake evaporation, and the Laurentide ice sheet both in the modern lake and paleohydrology.", "occurrence_notes":null, "guid":"153709-21916210@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/153709", "building_id":"1000188", "building_name":"1100 North University Building", "campus_maps_id":"628", "room":"2540", "location_name":"1100 North University Building", "has_livestream":0, "cost":"", "tags":["Dissertation","Earth And Environmental Sciences"], "website":"", "sponsors":[ { "group_name":"Earth and Environmental Sciences", "group_id":"3170", "website":"http:\/\/www.lsa.umich.edu\/earth" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/10\/event_153709_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/10\/event_153709_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/10\/event_153709_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/10\/event_153709_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/10\/event_153709_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/10\/event_153709_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_thumb\/media\/attachments\/2026\/10\/event_153709_original-1.png" }, "occurrence_count":1, "first_occurrence":21916210 } , "151937-21912485": { "datetime_modified":"20261016T182131", "datetime_start":"20261023T090000", "datetime_end":"20261023T100000", "has_end_time":1, "date_start":"2026-10-23", "date_end":"2026-10-23", "time_start":"09:00:00", "time_end":"10:00:00", "time_zone":"America\/Detroit", "event_title":"MPSDS Master's Info Sessions (2026)", "occurrence_title":"MPSDS Master's Info Session (First Session - 2026)", "combined_title":"MPSDS Master's Info Sessions (2026): MPSDS Master's Info Session (First Session - 2026)", "event_subtitle":"", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Interested in furthering your education in social research and data science?
