Among other awards and honors, Raymo became in 2014 the first woman to win the Wollaston Medal for geology, which had been awarded for 183 years at the time. She was described in her nomination as "... one of the foremost and influential figures in the last 30 years".[8]
Background
Raymo was born in Los Angeles[9] and attended Brown University, receiving her Sc.B. Geology in 1982. She then attended Columbia University, where she earned her M.A. in geological sciences in 1985, her M.Phil. in geology in 1988, and her Ph.D. in geology in 1989.[9]
Research

Raymo is also well known for her interdisciplinary work, particularly using
Scientific process
Maureen Raymo has “shaped our understanding of Earth’s natural climate variability and her many landmark papers have influenced a generation of climate scientists" states a biography by Columbia University in New York.[16] In her years as a graduate student, she began her career studying the history of ice ages, specifically the glacial/interglacial cycles that took place over the last few million years. “I would examine ice-rafted detritus material brought in by icebergs and try to figure out what it could tell us about how cold the Atlantic was through time.” (Aronsohn 2019).[17] She stated that these cores were “like a tape recorder through time” (Aronsohn, 2019). This work resulted in a series of papers in the late 80s and early 90s that published the first continuous high resolution records of Earth's climate history from oxygen and carbon isotopes.
In an analysis of collapsed polar ice sheets during the stage 11 Marine Isotope Interglacial (MIS), Maureen Raymo and Jerry Mitrovica computed global sea-level variations over the past 500 kyr. In their analysis, they assumed that the melting of the East Antarctic Ice Sheet (EAIS) and the Greenland Ice Sheet (GIS) happened towards the end of this interglacial period (Raymo & Mitrovica, 2012).[18] One of the methods they used in their examination involved using a “gravitationally self-consistent theory”. Additionally, the researchers performed a Monte Carlo parameter where they observed mantle viscosity, lithospheric thickness, and the duration of the break during MIS 11 (Raymo & Mitrovica, 2012). Raymo and Mitrovica have said that employing this method “yields a preferred bound on the peak eustatic sea level (ESL) during MIS 11” (Raymo & Mitrovica, 2012). Understanding the durability of existing ice sheets amidst climate change remains a significant concern for societal safety.
During the PLIOMAX project, Maureen Raymo formulated a method for correcting shorelines during the Pliocene period, for post-depositional isostatic changes (PLIOMAX, n.d.).[19] One of the main hurdles the PLIOMAX project faced was the ability to adjust and verify the model performance under CO2 and climate conditions (PLIOMAX, n.d.).[20] The accuracy of accessible paleoclimate data hindered these factors as mentioned earlier (PLIOMAX, n.d.). In another analysis, Maureen Raymo and her colleagues examined how polar ice sheets evolved during previous warm periods, specifically during the Pliocene period. For their research, the scientists examined existing evidence of previous sea levels and ice sheet constructions (Dutton et al., 2015). Despite many geological advances in the understanding of global mean sea level during previous warm periods, potential research hindrances still exist for future paleoclimate researchers. For instance, the peak heat temperatures during previous warm periods may have varied on the span of the respective interglacial period, which suggests that warm periods that lasted thousands of years may not represent “equilibrium conditions for the climate-cryosphere system” (Dutton et al., 2015). Additionally, it is currently not possible for researchers and scientists to make exact estimates of peak global mean sea level during the Pliocene period. In a research paper by Maureen Raymo and her colleagues, they explained that the majority of existing sea level projections focus on shorter timelines of <2000 years, however, longer timeline projections are critical for predicting potential future sea-level heights to effectively develop long-term sea level defense infrastructure (Kemp et al., 2015).[21] The demand to present location-specific details regarding future sea level projections in the midst of climate change is a critical aspect of climatology research because of the growing concentration of socioeconomic and residential activity along global coastlines (Kemp et al., 2015).
Scientific context
Maureen Raymo is known famously for her Weathering hypothesis. Maureen’s hypothesis consisted of mending the ideas of global cooling and the beginning of the ice ages to a decline in atmospheric CO2. The Tibetan plateau and the Himalayas are a direct cause of this. Raymo has also come up with a hypothesis concerning the flexibility and arrangement of ice sheets over a few million years.[22] Furthermore, Raymo was innovating new ways of researching previous sea level changes. Maureen’s focal point in her research had always been centered around identifying where and how the Earth's oceans, biogeochemical cycles, and climate have changed in previous years compared to models of past and future climate.
Awards and honors
Raymo is a fellow of the American Geophysical Union and the American Association for the Advancement of Science. In 2016 she was elected a member of the National Academy of Sciences.[4] Raymo has won various prizes for her scientific work, including becoming in 2014 the first woman to be awarded the prestigious Wollaston Medal - the highest award of the Geological Society of London.[8][23] In 2014, she received the Milutin Milankovic Medal at the European Geosciences Union’s annual meeting for her use of geochemistry, geology and geophysics to solve paleoclimatology’s big problems.[24] In 2019 she was awarded the Maurice Ewing Medal by the American Geophysical Union.[25] In 2022 she was elected as a Member of the Royal Swedish Academy of Sciences, Class for Geosciences.[26]
In 2002, she was included by the illustrated magazine Discover in a list of the 50 most important women in science[5][27] and in her nomination for the Wollaston Medal, Professor James Scourse described her as ".. one of the foremost and influential figures in the last 30 years...She's been an important role model to women scientists—you can get to the top".[8]
