9.- Adding NOAA's Word Ocean Atlas 2013 data to ModestR (Version ModestR 6.5 or higher)
- 1. Step by step tutorial: Adding NOAA's Word Ocean Atlas data to ModestR MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/
- 2. What do you need for this tutorial: 1. ModestR v.5.3 or higher installed 2. Internet connection 3. About 15 minutes ModestR software can be freely downloaded from http://www.ipez.es/ModestR MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/
- 3. We’ll describe how to download and install Word Ocean Atlas (from NOAA) data in ModestR . Follow the next steps! MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/
- 4. Download Word Ocean Atlas data specifically formated for ModestR from ModestR website: http://www.ipez.es/ModestR/Datafiles.html >> Data Files >> NOAA’s World Ocean Atlas 2013 or NOAA’s World Ocean Atlas 2018 MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/
- 5. Create a folder in your computer, called “WOA 1º Objectively analyzed mean All Decades” and decompress the downloaded file in this folder. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ Decompress Downloaded file Folder contents once file decompressed
- 6. As explained in the tutorial nº3 “How to integrate and use environmental data”, run ModestR MapMaker, go to the Layers >> Manage environmental variables menu option. A dialog box will be opened. Follow the steps: 1.Click on the Import button 2.Then select the Folder option in the menu that appears 3.Then select the folder created in the previous step:“WOA 1° Objectively analyzed mean All Decades” folder.
- 7. A new node will appear on the tree, with the same name than the imported folder MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ After importation, a new folder with the same subfolders and data that the folder we created in previous steps will be added to ModestR environmental variables
- 8. Expand the node to see the subfolders and variables imported. Each subfolder contains information about the variable at different depths. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/
- 9. Select a variable to see its details in the right panel. Each imported variable have an associated Z Value corresponding to its depth. This value has been extracted automatically by ModestR from the variable filename during importation. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ Z value associated to a variables
- 10. To be able to use variables for 3D analyses, you have to indicate to ModestR that each folder corresponds to a 3D variable. That is, each folder contains the same variable but for several depths (Z values). To do that, select each folder and convert it to a 3D dataset. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ 1. Select the folder corresponding to a variable and right- click to see a menu 2. In the contextual menu, select Convert folder to 3D dataset
- 11. An icon will indicate that the folder is now considered as a 3D dataset. Repeat the same steps with the other folders. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ 3D icon identifies a 3D dataset. Following the same steps, convert each one of the folders to 3D datasets
- 12. That’s it! Now you can create 3D compounded environmental layers (CEL’s) and calculate species distribution models using those 3D datasets too, as explained in the tutorials of ModestR. MODESTR QUICK TUTORIALS HTTP://WWW.IPEZ.ES/MODESTR/ Things to remember: 1. When creating a 3D CEL, only 3D datasets will be displayed among the candidate variables. 2. Variance Inflation Factor can be calculated, in order to detect collinearities between variables, and, eventually, delete redundant variables. This step is optional, and for this example we’ll just skip and continue. 3. For a 3D CEL, you can visualize each Z value (Z = depth in this case). You can also show a 3D view of the CEL. 4. The 3D CEL viewer allows you to interactively explore the 3D CEL in an easy way. 5. Close the 3D viewer and go back to MapMaker. Then continue to the last step of CEL creation. 6. You can eventually export a report about the CEL, and save the CEL in order to use it later. CEL’s can be used to calculate species niche or species environmental overlaps (see User’s Manual for more details).
