What are those straight lines in the ocean on Google Earth?

The lines on the ocean floor are locations where swaths of high-resolution sonar data are available. Since these strips of high-resolution data look different from the surrounding low-resolution data, they look like lines when you zoom out.

What are the lines on Google Maps?

Yellow lines on the map mean traffic is moving faster, from 25 to 50 miles per hour, while green lines mean traffic is zipping along at 50 miles per hour or more. If you see gray lines, that means there’s no traffic information available at the time and a red-black line refers to extremely slow or stopped traffic.

What are the lines in the South Pacific Ocean?

In the remote Pacific Ocean, a chain of coral islands and atolls straddling the Equator make up the ecologically diverse Line Islands. South of the Equator—called “the line” by sailors—lie five tiny isles: Malden, Starbuck, Vostok, Flint, and Caroline (or Millennium), known collectively as the southern Line Islands.

What makes ocean lines?

In the top image, long waves run parallel to the shore in alternating stripes of light and dark. These are the result of atmospheric gravity waves—waves that form in the atmosphere as a result of sinking and rising air. The troughs of the waves are ruffling the water’s surface, creating lines of rough water.

How do I see the ocean on Google Earth?

Open any web browser on your computer, and go to the Google Maps Ocean View website. View the available Ocean View locations. The underwater locations currently available are displayed on the right panel of your screen. Each of the locations is identified by its name, location, and a thumbnail image.

Does Google Earth show the ocean floor?

The ocean floors contain dramatic landscapes – volcanic ridges, lofty peaks, wide plains and deep valleys. Thanks to a new synthesis of seafloor topography released through Google Earth, armchair explorers can now view five percent of the deep ocean floor in far greater detail than ever before.

What are the yellow lines on Google Earth?

Yellow indicates speeds between 25 and 50 mph. Red means speeds are less than 25 mph. Gray means there is no data available. Black and red roads indicate traffic may be stopped at points.

What are the green lines on Google Earth?

Green: Dedicated lanes are roads that are shared with cars and have a separate bike lane. Dotted green line: Bicycle friendly roads are roads that don’t have a bike lane but are recommended for cyclists. Brown: Unpaved trails or off-road dirt paths.

Why is there a line in the middle of the ocean?

It’s the international date line and marks the boundary between the time zones that are +12 and -12 hours from UTC / Greenwich.

What is the South Pacific?

The South Pacific is the Southern Hemisphere portion of the Pacific Ocean, Earth’s largest oceanic division, and which includes several islands and archipelagos.

What is the line in the ocean called?

The geographic horizon is the apparent boundary between the Earth and sky. The ocean and the sky provide a clean, flat line where the Earth seems to meet the sky. If you’re standing on the beach looking out at the sea, the part of the sea that “touches” the horizon is called the offing.

Can Satellites see the ocean floor?

Satellites can “see the sea” in ways that are otherwise impossible. By remotely sensing from their orbits high above the Earth, satellites provide us much more information than would be possible to obtain solely from the surface.

Why are there straight lines on the surface of the ocean?

The detailed straight lines you’re seeing are “swaths”, the images captured by a high quality multi-beam sonar. The direction of the swath is due to the course of the ship. All that said, there are many fault lines, chasms and fractures in the sea bed, so sometimes a straight line is natural.

How can I see the ocean floor on Google Earth?

Viewers can use the “ground level view” feature of Google Earth to take them to the seafloor for a closer look at the terrain. To find which areas offer more detail, users can download a plug-in, the Columbia Ocean Terrain Synthesis.

How are the two straight lines on Google map measured?

The two straight lines are measured by multibeam, and the rest is measured indirectly by satellite gravimetry. The last being much more coarse than the first as it can be seen from the height curves. Straight lines on Google Map ocean bottom are the frontiers of the known ocean depths.

How to use Google Earth for storytelling?

Make use of Google Earth’s detailed globe by tilting the map to save a perfect 3D view or diving into Street View for a 360 experience. Collaborate with others like a Google Doc and share your story as a presentation. Adding placemarks and lines to Google Earth. Adding a photo to a place.
