Dragon Kings of the Deep Sea: Marine Particles Deviate Markedly From the Common Number-Size Spectrum
Particles are the major vector for the transfer of carbon from the upper ocean to the deep sea. However, little is known about their abundance, composition and role at depths greater than 2000 m. We present the first number-size spectrum of bathy-and abyssopelagic particles to a depth of 5500 m base...
