Atlas Tab — marine species atlas & fishing zones

Encyclopedia of marine species found in a chosen geographic area — with photos, habitat, seasonality and real occurrences — linked to the per-species fishing probability heatmap.

Where to find it

• Atlas (encyclopedia): Sidebar › Atlas tab (fish icon).
• Fishing Intelligence (heatmap): floating panel at the bottom-center of the map, opened via the Fishing Intelligence overlay from the map overlay panel.

The two features are linked: draw a zone from the fishing panel and analyze it in the Atlas; jump from a species in the fishing panel to its atlas sheet via the book icon.

Atlas Tab — species encyclopedia

How to use / Hide help

What it does: shows a built-in reminder of how the Atlas works (choosing a context, filters, the species sheet, the link with the fishing panel, data sources).

How to use it: 1. Click How to use at the top of the panel. 2. Read the box, then click Hide help to collapse it.

Options & settings: - Single toggle (amber text with info icon).

Tips & limits: the help reminds you that data come from OBIS, WoRMS, FishBase and iNaturalist (all free, CC-BY, no key).

Context (search area)

What it does: defines the geographic area in which the Atlas searches for observed species. Everything else (list, filters, sheets) flows from this choice.

How to use it: 1. Pick a context button in the grid at the top of the panel. 2. The active area label appears just below (e.g. "Visible area", "FAO 27 — …"). 3. The species list reloads automatically.

Options & settings:

• An expanded · … badge may appear next to the label: too few records in the area, so results come from a wider zone.

Tips & limits: the Zone and Route contexts depend on prior actions (draw a fishing rectangle, load a route). Hover a disabled button to see the exact prerequisite. FAO is the broadest and yields the most results offshore.

Text search

What it does: filter the list by name (scientific, English or French).

How to use it: 1. Type a few letters in the Search species… field. 2. The list narrows instantly.

Options & settings: single text field with a magnifier icon.

Tips & limits: the search matches scientific, English and French names simultaneously.

Type filters

What it does: restrict the list to a broad family of organisms. Each chip shows a species counter.

How to use it: 1. Click a chip (All, Fish, Mammals, Cephalopods, Crustaceans, Reptiles, Other). 2. Only chips present in the area are shown.

Options & settings: rounded chips with a count in parentheses; only one active at a time.

Tips & limits: families with no species in the area are hidden.

Filters (In season / Reachable depth)

What it does: refine the list by current month and by the boat's draft.

How to use it: 1. Toggle In season to hide species whose published season does not include the current month. 2. Toggle Reachable depth to hide species whose known minimum depth exceeds what your keel can reach.

Options & settings: - In season — toggle (calendar icon). - Reachable depth — toggle (waves icon). The label shows the computed limit, e.g. Depth ≤ 100 m.

Tips & limits: the depth filter is disabled until the keel depth is set in settings (the shown limit is derived from that value). Hover the disabled filter to see the reminder.

Species sheet

What it does: view a species in full detail and plot its occurrences on the map.

How to use it: 1. Click a species card in the list. 2. The sheet opens; use Back to the list (arrow) to return. 3. While the sheet is open, OBIS occurrence points are plotted on the map; pan/zoom to refresh.

Options & settings: - Photos — up to 6 community thumbnails (click through to the source). - Stats — max size, typical size, max weight, depth range, environment (Marine / Brackish / Freshwater / Euryhaline), trophic level, body shape, game fish, commercial importance, observation count. - Warning — red box if the species is dangerous. - Seasonality — histogram of observations per month. - AI enrichment — Generate (then Regenerate) button to produce text on fishing techniques, edibility, identification and rules. Cancel button during generation; Saved marker once cached. - Source links — OBIS, FishBase, WoRMS, iNaturalist (open in the browser).

Tips & limits: the AI enrichment is cached locally for 30 days and reloads instantly afterwards. Photos depend on community observations in the area: a message shows when there are none.

Fishing Intelligence — probability heatmap

Species selector & heatmap

What it does: estimate, over a colored grid, the per-species probability of presence by combining oceanographic factors (SST, chlorophyll, depth, fronts) with temporal factors (season, moon phase).

How to use it: 1. Enable the Fishing Intelligence overlay from the overlay panel; the floating panel appears at the bottom-center of the map. 2. Click Draw zone, then drag on the map to trace a rectangle (release to commit). 3. Cells color progressively as scores arrive. 4. Toggle species in the selector: the map recolors instantly (no recompute). 5. Hover a cell for the score, click it for the per-species detail and factors.

Options & settings: - Today's moon phase + API budget (Copernicus WMTS + Open-Meteo counter). - Draw zone / Redraw zone / Cancel / Clear zone. - Species buttons: Tuna, Mahi-mahi, Mackerel, Sea bass, Bonito (a ☾ crescent flags a species out of season this month). - Open in atlas (book icon on each species) — jumps straight to that species' atlas sheet.

Reading the heatmap:

Clicking a cell shows the raw factors (SST, chlorophyll, depth, sea-level anomaly, gradient) and a score per selected species.

Tips & limits: the tool is heuristic — local knowledge always trumps remote sensing. The fishing panel's species selector (5 species) is distinct from the Atlas list (every observed species in the area): don't confuse the probability map (5 fishing targets) with the encyclopedia. A tiny rectangle (accidental click) is ignored.

The Atlas ↔ Fishing Zones link

What it does: circulate the same zone and the same species between the two tools.

How to use it: 1. Draw a zone from the Fishing Intelligence panel; in the Atlas, pick the Zone context to list every species actually observed inside that rectangle. 2. Conversely, from the fishing panel, click a species' book icon to open its atlas sheet directly. 3. Selecting a species in the Atlas is mirrored on the map (OBIS occurrence plot).

Tips & limits: only one fishing zone is active at a time; redrawing it replaces the previous one.
