Where the particles were found

Each square pools the tows that crossed it (0.02° (≈ 2 km) cells). Colours are the lower, middle and higher third of the squares in this programme's own data; there is no safe/unsafe threshold. Tap a site name for its report card.

Publications and dataset details

What these numbers can and cannot say

  • Counts are raw. Control samples (nets and filters exposed without sampling) were collected and are shown alongside the data, but nothing has been subtracted from the sample counts.
  • Concentrations count the particles that passed a hot-needle melt test (the lab's basis); every particle picked is available in the Advanced view.
  • Manta nets sample the surface and keep particles larger than the mesh (330 µm, about a third of a millimetre). Smaller particles are not counted here.
  • Data describe specific sites and dates; they are not a bay-wide or year-round average, and they say nothing about health or safety.
