 he ocean\n        \n\n    \n\n              \n\n\nAbstract: Plastic waste 
 accumulating in the global ocean is an increasingly threatening environmen
 tal issue. Transported by currents\, wind and waves\, positively buoyant p
 lastic objects eventually accumulate at the sea surface of subtropical oce
 anic gyres\, forming the so-called ocean garbage patches. To date\, the fl
 oating and thus most visible fraction of ocean plastic pollution has been 
 mapped at global scale. Yet\, current estimates of plastic debris that is 
 afloat at sea account for less than 1% of all the plastic that is believed
  to have entered the ocean since the 1950s. A major fraction of positively
  buoyant plastic debris is therefore currently unaccounted for\, suggestin
 g that there are unrecognized pathways that lead to loss of plastic from t
 he ocean surface. The unaccounted plastic debris is hypothesized to be sus
 pended at intermediate depths in the ocean water column\, to have been dep
 osited on the seabed\, to have been captured in coastal environments\, or 
 to have fragmented into smaller micro- and nano-sized particles that escap
 e current sampling techniques. However\, the plastic mass in each of these
  reservoirs and the corresponding plastic fluxes remain unknown. In this p
 resentation\, I will summarize the current state of knowledge concerning t
 he transport and transformation processes of positively buoyant plastic de
 bris in the ocean. Such knowledge is of paramount importance to assess the
  long-term risks of ocean plastic pollution for marine ecosystems\, fisher
 ies and food supply to humans\, as well as to advance optimized mitigation
  strategies.\n\n\n\nJoin Zoom Meeting https://zoom.us/j/96105792609?pwd=Qm
