{"product_id":"9781495925368","title":"Oceanographic Controls on Sedimentary and Geochemical Facies on the Peru Outer Shelf and Upper Slope","description":"Concentrations and characteristics of organic matter in surface sediments deposited under an intense oxygen-minimum zone (OMZ) on the Peru margin were mapped and studied in samples from deck-deployed box cores and push cores acquired by submersible on two east-west transects spanning depths of 75 to 1,000 meters (m) at 12°S and 13.5°S. On the basis of sampling and analyses of the top 1-2 centimeters (cm) of available cores, three main belts of sediments were identified on each transect with increasing depth: (1) muds rich in organic carbon (OC); (2) authigenic phosphatic mineral crusts and pavements; and (3) glaucony facies.","brand":"CreateSpace Publishing","offers":[{"title":"Default Title","offer_id":48533420048625,"sku":"9781495925368","price":16.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/5433\/7265\/files\/9781495925368_p0.jpg?v=1786319454","url":"https:\/\/shop.barnesandnoble.com\/products\/9781495925368","provider":"Barnes \u0026 Noble","version":"1.0","type":"link"}
