Ocean Cross Section

Caption

An influx of nutrients to the ocean -- catalyzed by higher temperatures -- stimulates organic matter production and subsequent decomposition, consuming oxygen in the process. This is thought to be primarily responsible for large-scale oxygen loss in ancient oceans, leading to mass extinctions in the marine environment. Unfortunately, the modern ocean is exhibiting similar symptoms.
