You can view bathymetric data, such as depth values in meters, and features, such as trenches, sea ridges, and seamounts. Notable features mapped include Challenger Deep, the deepest known area of the ocean floor, which film director James Cameron visited in March 2012 aboard the deep-sea submersible\u00a0Deepsea Challenger<\/em>.\r\n\r\nThe bathymetry data displayed above comes courtesy of the University of New Hampshire.\r\n\r\nBut the Ocean Basemap goes beyond being just an exploratory tool that displays subsurface features, water bodies, and depth values. Data can be overlaid on it to perform a spatially based analysis of an almost limitless variety of data, whether posted on\u00a0ArcGIS Online<\/a>\u00a0or maintained by you or your organization.\r\n\r\nThis tip walks you through how to visually analyze data overlaid on the Ocean Basemap. For this scenario, you will use both pipeline and fishing restriction data for the Gulf of Mexico to help you answer two simple questions: How can commercial fishing and the oil and gas pipelines coexist there? And how can the captain of a commercial fishing boat avoid oil and gas pipelines so as not to endanger the crew or vessel or badly damage a cable or pipeline by snagging it with ropes, nets, or anchors? Such an event could be expensive and dangerous to the boat, the crew, and the equipment that belongs to another business (the owner of the pipe or cable). The accident might affect the regional economy if damage to the industrial equipment necessitated a stoppage for repairs, and if a spill occurred, there might be environmental damage.\r\n\r\nStep 1:<\/strong>\u00a0Log in to ArcGIS Online at ArcGIS.com using either your organization's ArcGIS Online subscription or a personal account.\r\n\r\nStep 2:<\/strong>\u00a0Create a new map by clicking the Map button on the toolbar.\r\n\r\n\r\n\r\nStep 3:<\/strong>\u00a0To add the Ocean Basemap, click the Basemap button. A number of basemaps will appear in the gallery. Select Oceans.\r\n\r\n\r\nYou've just created a web map with the Ocean Basemap as a canvas to work on, as seen here.\r\n\r\n\r\n\r\nStep 4:<\/strong>\u00a0Find pipelines data using ArcGIS Online to see the locations of the natural gas and oil pipeline distribution network.\r\n\r\nClick the Add button and select Search for Layers from the drop-down list. Search ArcGIS Online by typing in\u00a0pipelines by product<\/em>. Click Go.\r\n\r\n\r\nThe results will include Active Pipelines by Product in U.S. Waters. Click Add to place the data in the web map.\r\n\r\nYour web map should look like the live one below.\r\n\r\n
