World Map With Latitude And Longitude Interactive – You are here: Home 1 / OOI Lab Exercise 2 / Lab 1 – Ocean data collection 3 / Lab 1.3

Prerequisites: A printed world ocean map and activity maps with a ruler or ruler are helpful but not required. Additional examples of latitude and longitude are required for proficiency.

World Map With Latitude And Longitude Interactive

We use our cell phone or use our car to navigate to an address, but how does the phone know its location? But if we are at sea without any roads or road signs, how do oceanographers know where we are in the great blue ocean with no land to see? Global Positioning Systems, also known as GPS, use satellites to locate locations on Earth. Many satellites are used to determine our position using a series of coordinates covered on the Earth’s surface called latitude and longitude.

Latitude is a line starting at the equator or 0 degrees (°) of latitude. East and west latitudes are parallel to the equator and are measured in degrees north or south of the equator at 90 degrees north or south. Latitude lines are far from each other. A degree of latitude is divided into 60 minutes (‘). A minute of latitude is 1.15 miles or 1 nautical mile. A minute of latitude is divided into 60 seconds (”). We indicate latitude in degrees, minutes and seconds with north (+) or south (-). For example: 27 degrees 12 minutes 28 inches north. North degrees are called Northern Hemisphere and South degrees are called Southern Hemisphere. We also divide the world according to climate into tropical (0-23.5°N or S), subtropical (23.5-30°N or S), tropical (30-60°N or S) and arctic (60-90 North or South degree) we divide. S). S). Although these cut-off latitudes are not exact, they can vary between 5 and 10 degrees and provide a visual representation of the four physical and chemical climate zones important to wildlife.

Now that we know how far north or south of the equator we are, we need to know a more precise location. After all, we can be anywhere in the world at the same latitude. The second part of the grid system we use is called Longitude. Lines of longitude or meridians extend from the North Pole to the South Pole. Unlike the equator, which is the center of the Earth, the prime meridian, or 0° longitude, is fixed to use Greenwich, England. This city has moved many times in history to tour other big cities. Lines of longitude run north and south from pole to pole, meaning they are not the same at different latitudes, they are farther apart at the equator than at the poles. It takes 24 hours to complete one revolution or 360 degrees. So every hour the Earth rotates by 15 degrees of longitude (360 degrees / 24 hours = 15 degrees per hour). Longitude is measured east or west of the prime meridian at 180 degrees from the anti-meridian or international date line. Longitude is written in degrees, minutes and seconds and east (+) or west (-) of the prime meridian. For example: 85 degrees 15 minutes 32 inches west.

Graphing Latitudes And Longitudes Using Python

With the latest digital technology, latitude and longitude can also be displayed in decimal form. If you’re plotting locations on a map with software, you’ll need to convert them using one of the online latitude and longitude converters. Just remember that in decimal you will use positive (+) for east and north and negative (-) for west or south. For our purposes, we use historical degrees, minute and second settings. When you write a location, you must include both latitude and longitude, starting with the first latitude. For example: 27 degrees 12 minutes 28 inches north, 85 degrees 15 minutes 32 inches west. Remember you will get lost without basic directions (North, South, East, West)!

When looking at maps, it is important not only to note coastlines, sea basins, and ocean features, but also to note the longitude and latitude measurements for that particular map. Similar to specifying the scale on the x- or y-axis for a chart, scale points or points between two degree numbers can be degrees, minutes, seconds, or a combination based on the approach to a location on the map. First, let’s look at a simple example. Click on the question marks to learn more about reading these latitude and longitude measurements. Remember that 1 degree is equal to 60 minutes, which is the same clock count where 1 hour is 60 minutes and 1 minute is 60 seconds! (Just change “hours” to degrees and degrees on Earth are more than hours in hours because they are based on angles – but, I think you get the idea!) You can use this information to determine the measurement by looking do. How many degrees or marks are there between longitude or latitude on the scale? You can calculate a small scale between the tick marks.

Let’s see some examples on real maps. Note Figure 1.3.4 below: On the A scale, the longitude and latitude marks are the same, 30 minutes or 1 degree every 2 marks. On the B scale, the latitude is different and the longitude, the latitude marks are 15 minutes each and the longitude is 20 minutes or 1 degree every 3. Paying attention to the direction of increase or decrease is also important. In the A dimension, your latitude is increasing from the top to the bottom of the image, and in the B dimension you are decreasing the latitude from the top to the bottom of the image.

Use the maps below (Figure 1.3.6-1.3.9) to determine the calculated longitude and latitude, in degrees (°) and minutes (‘) given the size of the four maps, for the web buttons in each OOI array. . Remember to include N, S, E or W direction. Find the latitude and longitude of the center of the circle next to the network name.

Each OOI array consists of stations, platforms, and devices at different latitudes, longitudes, depths, distances from shore, or other geographic locations. Some tools are portable, while others are fixed. For example, in Lab Activity 1.4, you will learn about zooplankton migration during the solar eclipse on August 21, 2017. The data collected to detect this phenomenon is collected in the endurance array. The Coastal Endurance array features the Oregon and Washington line. The Endurance Array is a large array that uses fixed and mobile assets to monitor horizontal and shelf-to-shelf shipping off the Oregon and Washington coasts. The line also provides an international footprint that includes an existing eastern boundary and connects to the OOI cable array. The image below shows the entire Endurance Array.
