The Reef Report

A story about marine science, citizen monitoring and respecting fragile places.

When Kiri was thirteen, her aunt, a marine biologist, invited her to join a school-holiday volunteer trip on the Great Barrier Reef. They were going to survey a patch of coral, and Kiri could help. She packed her snorkel and notebook, and could hardly sleep.

On the first morning, the boat chugged out from the harbour. The water was a deep, shimmering turquoise. The leader, Dr Naidoo, gave them a safety talk. “Always stay with your buddy,” she said. “Never touch the coral, or stand on it. It is a living animal, and it is fragile.”

Kiri slipped into the water, and put her face under. A new world opened. She saw branching coral, round brain coral, and soft fans waving in the current. Shoals of yellow and blue fish darted among them. She almost forgot to breathe.

Her job was to help with a survey. They stretched a long measuring tape along the bottom, and Kiri used a waterproof slate to record what lay under the tape at every half metre. Hard coral, soft coral, algae, sand. It took patience.

At one point, she noticed a patch of white coral. It looked like bone. “What happened to that?” she asked, back on the boat. “It is bleached,” said Dr Naidoo. “When the water gets too warm, the coral loses the tiny algae that give it colour and food. It can recover if the water cools.”

Kiri felt a pang. The reef was beautiful, but it was in trouble. “What can we do?” she asked. “Study it, so we understand it,” said Dr Naidoo. “And reduce the things that warm the planet. Every bit helps.”

For three days, they recorded data. Kiri learned to identify twenty species of fish and eight types of coral. By the end, she could tell a butterflyfish from an angelfish at a glance. She filled her notebook with sketches and notes.

On the last night, Dr Naidoo showed them how the data would be added to a long-term record that tracked changes in the reef over years. “Your numbers are part of this,” she said. Kiri felt a warm glow of pride.

Back home, she gave a talk at school. She showed her photos and her sketches. “The reef is beautiful and fragile,” she told her classmates, “and it needs us to care.” Afterwards, six of them asked how to get involved.
