To answer that question, my talk with will pivot around two topics: internal tides and the billion-dollar NASA Surface Water and Ocean Topography (SWOT) mission. Internal tides are generated by tidal flows interacting with seafloor topography, causing vertical displacements at the boundaries between layers of differing oceanic densities. Breaking internal tides lead to subsurface ocean mixing which in turn exert a strong control on oceanic stratification, the meridional overturning circulation, and the storage and transport of heat and carbon in the ocean. Despite being most pronounced below the sea's surface, these internal tides also create a measurable sea surface height (SSH) signature, detectable by satellite altimetry. The advent of the SWOT mission has enabled us to observe the ocean with unprecedented resolution. To discern the wealth of information contained within the satellite observations, it is crucial to isolate and remove the internal tide signals. Our research demonstrates that supercomputer-generated ocean forecast models can effectively extract internal tide SSH contributions from satellite altimetry data, offering a skill level on par with direct satellite data analysis. The fundamental benefit of utilizing these models is their capability to reveal comprehensive ocean water column characteristics with high temporal resolution, a feat satellites cannot achieve. This capability presents an exciting opportunity to enhance our understanding of oceanic processes at scales never before possible.", "occurrence_notes":null, "guid":"108208-21819110@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/108208", "building_id":"1000188", "building_name":"1100 North University Building", "campus_maps_id":"628", "room":"1528", "location_name":"1100 North University Building", "has_livestream":0, "cost":"", "tags":["Natural Sciences"], "website":"https:\/\/twitter.com\/MichiganEarth", "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\/2024\/02\/event_108208_original-1.jpeg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/02\/event_108208_original-1.jpeg" }, "occurrence_count":1, "first_occurrence":21819110 } , "119598-21843053": { "datetime_modified":"20240329T181529", "datetime_start":"20240329T160000", "datetime_end":"", "has_end_time":0, "date_start":"2024-03-29", "date_end":"", "time_start":"16:00:00", "time_end":"", "time_zone":"America\/Detroit", "event_title":"Baseball vs Maryland", "occurrence_title":"", "combined_title":"Baseball vs Maryland", "event_subtitle":"", "event_type":"Sporting Event", "event_type_id":"20", "description":"Baseball vs Maryland", "occurrence_notes":null, "guid":"119598-21843053@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/119598", "building_id":"1000733", "building_name":"Ray Fisher Baseball Stadium", "campus_maps_id":"134", "room":"", "location_name":"Ray Fisher Baseball Stadium", "has_livestream":0, "cost":"See MGoblue.com", "tags":["Athletics","Athletics -

We approach this question from the perspective of the so-called lattice point counting problem for the mapping class group acting on Teichmuller space, which concerns the number of group elements that send a given point into a ball of radius R about another point. In the case of a closed surface of genus g, Athreya, Bufetov, Eskin, and Mirzakhani have shown that, for the whole mapping class group, this quantity is asymptotic to exp((6g-6)R) as R tends to infinity. Maher has obtained the same asymptotics for those orbit points that are translates by pseudo-Anosov elements. We consider the remaining Nielsen-Thurston types: For finite-order elements we show the associated count grows coarsely at the rate of exp((3g-3)R), that is with exactly half the exponent, and for reducible elements it grows at the rate exp((6g-7)R). In order to achieve this, we introduce a new notion of \"complexity length\" in Teichmuller space which has several interesting features reflecting aspects of negative curvature.
