The Niskin bottle is a crucial tool used in oceanography for collecting water samples from various depths in the ocean. Named after the marine biologist Shale Niskin, this device allows researchers to obtain uncontaminated samples of seawater for a wide range of scientific analyses.
Design and Function
The Niskin bottle is usually made of transparent plastic or metal and consists of two tubes connected by a rubber seal. When deployed into the ocean, the bottle is open at both ends, allowing water to flow freely through it. By triggering a mechanism on the surface, a researcher can close both ends simultaneously, capturing a sample at a specific depth.
Usage
Researchers typically deploy Niskin bottles on a line, known as a rosette, to collect water samples at multiple depths simultaneously. This allows for the study of various properties of seawater, such as temperature, salinity, dissolved oxygen, and nutrient concentrations.
Accuracy
One of the key advantages of the Niskin bottle is its ability to collect samples without introducing contamination from the surface or the surrounding water. This feature ensures the accuracy of the data collected and allows researchers to make reliable conclusions based on their analyses.
Research Applications
The Niskin bottle is used in a wide range of oceanographic studies, including climate research, marine biology, and ocean chemistry. By providing researchers with access to pristine water samples from various depths, this tool plays a crucial role in advancing our understanding of the world's oceans and their impact on global systems.
