As Los Angeles has grown from a small town to an urban giant of more than 15 million residents over the last 100 years, researchers and managers have wondered about the fate of the deep waters and sediment of Santa Monica Bay. University of Southern California (USC) Sea Grant funded researchers at USC and the University of California Los Angeles to map the deep water oxygen content and changes over time of Santa Monica Bay using sediment cores. <\/span><\/p>\n\n\n\n<\/div>\n      \n      \n    <\/div>\n  \n  \n  \n\n  <\/div><\/div>\n\n\n\n\n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--rich-text \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--rich-text\"\n    \n      >\n\n    \n      \n<div class=\"f--field f--wysiwyg\">\n\n    \n  <h3><b>Key Results:<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">There has been little change in deep sediment oxygen in Santa Monica Bay over the last 100-120 years<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Low oxygen has not spread in the deep sediments of Santa Monica Bay<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Project Impacts &amp; Application:<\/b><\/h3>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Results were presented at the Southern California Geobiology Symposium<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">An <a href=\"https:\/\/faculty.epss.ucla.edu\/~ttreude\/?p=268\">educational display<\/a> of sample sediment cores was created for public education at the Santa Monica Aquarium <\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">A <\/span><a href=\"https:\/\/youtu.be\/xg7XT3bfD0U\"><span style=\"font-weight: 400;\">YouTube video<\/span><\/a><span style=\"font-weight: 400;\"> highlighting these interesting project methods was created for public education\u00a0<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><b>Principal Investigators<\/b><span style=\"font-weight: 400;\">:\u00a0<\/span><\/h3>\n<ul>\n<li><span style=\"font-weight: 400;\">William M.
