A Walt Whitman High
School sophomore will get a chance to follow through on his proposal to prevent
brown tide in the Great South Bay after being accepted into Barcode Long
Island.
Andrew Lorente’s next
steps will include “collecting algae samples from the Great South Bay and
identifying species that cause this brown tide. He will then isolate and
identify the algae at Whitman, extracting their DNA and barcoding them to
confirm the specific species.”
According to the
Barcode Long Island program: “[Lorente’s proposal came from an interest in the
topic in the summer of 2020. There was an algae bloom on the broadside of the
bay and his mom informed him of the occurrence. Lorente then chose brown tide
from the Great South Bay as his research topic in 2021 and has continued
since.”
The DNA Learning Center
program invites high school students to gain an intuitive understanding of the
crucial interdependence between humans and the natural environment. It
collaborates with Stony Brook University, Brookhaven National Laboratory and
the American Museum of Natural History.
FROM BARCODE:
Currently, Lorente is
still collecting samples, studying them under a microscope, and collecting
data. Most recently, he is trying to grow algae from these samples to figure
out what variables can help algae growth.
“I’m looking forward to
seeing results and how we could potentially stop or slow down the growth of
algae,” Lorente said.
He said that although
brown tide doesn’t directly affect humans, it affects a lot of sea life like
oysters. However, Lorente mentioned in Florida that a red tide algae bloom
occurred, and in this instance, it had a direct effect on humans. This project
is important in understanding these algae blooms and how to avoid them from
happening.
After receiving
results, Lorente will send his findings back to Barcode Long Island, and he
will then use DNA barcoding and other materials to identify the type of algae he
has grown.
