The National Geographic Travel Photographer of the Year Contest is open to submissions until the end of this week, June 30. The grand-prize winner will receive a 10-day trip for two to the Galápagos Archipelago with National Geographic Expeditions. National Geographic was again kind enough to allow me to share more of the entries with you here, gathered from three categories: Nature, Cities, and People. The photos and captions were written by the photographers, and lightly edited for style.

1. Brazilian Surfer Letting a Wave Pass - It was an ideal day for surfing just off of Rio de Janeiro's iconic Copacabana beach, and this man was making the most of it, catching wave after wave. I had my point-and-shoot trained on him since he was smoothest and most skillful of the wave riders, and caught him passing through a wave while he was waiting a better one in an oncoming swell.

4. Fast Food - After many hours with this mother fox, I gained her trust. I noticed her posture changed all of a sudden and in the blink of an eye she pounced into a hole and came out with a rabbit for her kits. As she left to deliver the food, she looked back at me as if to show off her catch - an amazing wildlife experience.

6. Eye Spy - This photograph captures a whale behavior called "spy hopping", where whales poke their head above the water to take a look around and see what is happening above the surface. It's like these majestic mammals of the sea understand we were watching them and were trying to connect with us in some way. In this shot, I wanted to capture this by showing the whale between two worlds, ours above the surface and its below, at the precise moment when it is about to make that connection.

7. Walled City #08 - The Kowloon Walled City was the densest place on Earth. Hundreds of houses stacked on top of each other enclosed in the center of the structure. Many didn’t have access to open space.This notorious city was finally demolished in 1990s. However, if you look hard enough, you will notice that the city is not dead. Part of it still exists in many of current high density housing apartments. I hope this series can get people to think about claustrophobic living in Hong Kong from a new perspective.

8. The Power of Nature  - Powerful eruption of Colima Volcano in Mexico on December 13, 2015. That night, the weather was dry and cold, friction of ash particles generated a big lightning of about 600 meters that connected ash and volcano, and illuminated most of the dark scene. On last part of 2015, this volcano showed a lot of eruptive activity with ash explosions that raised 2-3 km above the crater. Most of night explosions produced incandescent rockfalls and lightnings not bigger than 100 meters on average.

11. Solidified Lava vs Forest - I shot this picture in Sicily, with my drone. Those waves of lava are from Etna's big eruption back in 2002, this eruption was so spectacular that was recorded by Lucasfilm and integrated into the landscape of the planet Mustafar in the 2005 film Star Wars: Episode III.
