Hawaii is recognized worldwide for having beautiful beaches with brilliantly blue, crystal-clear ocean water. Have you ever wondered what makes Hawaii's ocean water SO blue compared to other beaches around the world?
There are several factors that affect the color of ocean water and Hawaii has the perfect balance of these factors to create some of the most memorable and beautiful ocean blues.
Factors That Affect the Color of Ocean Water
It’s a common misconception that the ocean is blue because it reflects the blue color of the sky. Sometimes the ocean looks green or teal or brown which are not the colors of the sky. Even when the sky is cloudy the ocean still looks blue, right? So let’s take a closer look at the factors that actually affect the colors of the sea:
- Light absorption
- Presence of algae
- Sediment in the water
When the sunlight hits the ocean, some of the photons from the light are absorbed by the water. Colors with long wavelengths are absorbed first, like red, orange, and yellow. The photons with short wavelengths, colors like blue and indigo, aren't absorbed. These are the colors we see reflected in the water.
In shallow bodies of water where the light penetrates completely (imagine a glass of water), photons aren’t absorbed at all and the water appears colorless. The deeper the water, the more colors are absorbed, and therefore we see darker and darker shades of blue.
But the ocean isn’t always blue. Sometimes it appears green. This is due to a high presence of phytoplankton in the water. Phytoplankton is a microscopic algae and a source of food for a wide range of ocean animals. Phytoplankton absorbs red and blue light as part of its photosynthesis and reflects green light. The more phytoplankton the greener the water appears, the less phytoplankton, the bluer it is.
Sediment and floating particles like sand, silt, algae, and even corals affect the water clarity and how much light is absorbed. This changes the color of the water we see and can make it look green or even brown.
So Why is Hawaii's Ocean So Blue and Clear?
Hawaii is famous for stunning beaches with brilliantly blue and clear ocean water. There are several reasons, based on the three factors above, why Hawaii's water appears more blue than other coastlines around the world.
- The coral reefs that surround Hawaii protect the coastline from strong waves and water currents that would otherwise stir up sand and sediment. This helps to keep Hawaii’s ocean water clear.
- The sediment in Hawaii’s oceans is made up of volcanic rock, coral, and shells which are heavy and not easily stirred up. The sediment quickly settles on the ocean floor, keeping the water clear.
- Hawaii’s ocean water is nutrient deficient. This is common in tropical areas with warm surface water temperatures. A lack of nutrients means there are fewer phytoplankton and algae in Hawaii’s water, which makes it more blue.
For these reasons, Hawaii’s ocean water is able to absorb and reflect light better and without interference, making it clear and beautifully blue.
3 Water Photography Tips
The clarity and vibrant blue color of the ocean make it a popular subject for photography. Here are three water photography tips to help you capture the best images of Hawaii’s ocean.
- Use a polarizing filter. This will reduce glare from the water, boost color intensity, and highlight the water’s texture and details.
- Try different shutter speeds. A fast shutter speed will freeze the water movement, a good strategy for capturing the power of ocean waves. Use a slow shutter speed to create a flowy, silky effect and convey the motion of the water.
- Experiment with intentional camera movement. This technique is great for creating abstract water photography. With your camera set to a slower shutter speed, move the camera while the image is being taken to create a blurred effect.
Don’t have a DSLR camera? That’s okay! They make polarizing filters for camera phones and these effects can be achieved by using the manual or “pro” setting on your phone’s camera to adjust the shutter speed.
The clarity of the ocean also creates ideal conditions for underwater photography. You can get a mesmerizing view of life under the ocean including coral reefs, tropical fish, turtles, and even whales!
Fine art photography prints offer a unique and stunning visual representation of Hawaii's most prominent natural feature, capturing the beauty and serenity of its waters. Decorating your home or office with ocean images is a great way to incorporate natural features and imbue your space with the calming serenity of Hawaii’s oceans.
