Fig 1.
Map of the Hawaiian Archipelago.
Top panel showing the Hawaiian Archipelago domain of the dispersal model with the major surface currents (in green) identified (after Lumpkin 1998). Bathymetry lines denote 1000 and 50 m isobaths. Bottom panels show coral reef habitat pixels for the Northwestern Hawaiian Islands and Main Hawaiian Islands respectively, with each island's habitat pixels shown as a separate color. Bathymetry lines in NWHI denote 50m depth isobath.

Fig 2.
Potential Connectivity matrix for the Hawaiian Archipelago.
(A) The values in each cell are “settlement” probabilities scaled to the receiving site for year-round particle release. Arrows indicated the breaks mentioned in the text. Each row in the matrix adds up to 1. High values (red) indicate high connectivity and low numbers (blue) indicate low connectivity, and white cells denote no connectivity. (B) Difference matrix showing the difference in connectivity between year-round and May-June particle release. The May-June release matrix is subtracted from the year-round release matrix (in A above). Positive values (red) denote a higher connectivity value for year-round releases and a negative number (blue) denotes higher connectivity for May-June released particles.
Fig 3.
Total percent successful settlement for all sites in the Hawaiian Archipelago for the five-year model run.
The green bars represent particles spawned during peak spawning season May-June each year.
Fig 4.
Total percent successful settlement at each island for the five-year model run.
Green bars show settlement for particles spawned during May-June, gray bars show settlement for year-round spawning.
Fig 5.
Density kernel for dispersal distance from source site for all islands for the five-year model run.
Green kernel denotes May-June spawning and gray kernel year-round spawning.
Fig 6.
Island specific mean particle dispersal distances from the source island.
Green color denotes particles released during May-June and gray denotes distances for year-round release.
Fig 7.
Island specific self-recruitment for the five-year model run.
Green bars show self-recruitment for particles spawned during May-June, gray bars show self-recruitment for year-round spawning.
Fig 8.
Source-Sink index for all islands in the Hawaiian Archipelago for the 5-year model run.
Positive numbers indicate a net source location, and negative numbers indicate a sink location. Green color denotes particles released during May-June of each year and gray denotes distances for year-round releases.

Modeled flow fields produced by the regional Hawaiʻi MITgcm for May 2009-May 2014.
Surface geostrophic currents (m/s) around the Hawaiian Archipelago. The eastward zonal flows are visible near 25°N and 27°N. Major surface currents are marked: Hawai‘i Lee Counter Current (HLCC), Hawai‘i Lee Current (HLC), North Equatorial Current (NEC) and North Hawaiian Ridge Current (NHRC). Vectors show current velocities and colors denote current speeds.
