The ocean takes a deep breath.
Deep convection is the major mechanism for replenishing oxygen in the deep interior of the world ocean, and its variability affects the use of atmospheric oxygen to monitor the global carbon cycle. Sensors mounted on autonomous floats allow this episodic breathing of the ocean to be monitored in near real time. The results suggest that the tools are available now to make oxygen a key parameter ...

Autoimmune targeting of a lung-specific protein can cause interstitial lung disease (Shum et al., this issue).
متن کاملThe Deep Atlantic Ocean
The Atlantic Ocean is a long sinuous ocean which originated during the Mesozoic following the breakup of the supercontinent of Pangea. For most of its length, the eastern and western boundaries are clearly defined by land masses, except where it is separated from the Caribbean Sea and Gulf of Mexico by troughs and trenches. The northern and southern limits are more difficult to define. To the n...
متن کاملTake a deep breath: pulmonary research inspires.
The lung is a complex organ with multiple functions; in addition to facilitating gas exchange, it also serves as the first line of defense against inhaled environmental pathogens and toxins. Given these critical roles, disruption of normal cell function or cell-cell interactions can have devastating health consequences. The articles of this Review Series highlight recent progress in understandi...
متن کاملDeep Convection in the Ocean
SCIENTIFIC OBJECTIVES Issues specific to oceanic deep convection are the relatively strong role of rotation, such that convective Rossby numbers appropriate to the vertical motions may fall below unity; the highly intermittent nature of the forcing, with the strong impulses coming during the passage of atmospheric weather systems; the possible highly localized occurrence of deep convection; and...
