1977 study analyzed North Atlantic ocean sediments over 200,000 years. Published 1977 by Ruddiman, Sancetta, and McIntyre Analyzed planktonic foraminifera assemblages from ocean sediments Examined response rates of subpolar North Atlantic waters over 200,000 years
A groundbreaking 1977 study by Ruddiman, Sancetta, and McIntyre analyzed planktonic foraminifera from ocean sediments spanning 200,000 years. Their research tracked how subpolar North Atlantic waters responded to climate changes, revealing migration patterns of the Atlantic polar front. The study identified three prominent rapid climate shifts over this vast timeframe, fundamentally changing our understanding of glacial-interglacial cycles.
